Research Focus:

• Establishing ocular Diagnostic Center


• Execute research studies on genetic eye diseases of national importance, resulting in blindness.


• Understanding the molecular mechanisms of complex eye disorders like myopia, age related macular degeneration, glaucoma, Fuchs’ endothelial corneal dystrophy and diabetic retinopathy.


• Establishing ocular disease DNA bank.

Research Highlights

Research on genetics of various eye diseases involves gene mapping employing high throughput next generation sequencing based techniques involving traditional linkage analysis / homozygosity mapping in families, targeted resequencing , whole exome sequencing approaches for the identification of novel genes in inherited ophthalmic diseases.

GENETICS OF INHERITED RETINAL DYSTROPHIES

At the Genetic department, we have a well-organized pedigree database and DNA bank of patients with various inherited ocular conditions. Gene mapping studies carried out on the families identifed at our department, has led tot he discovery and involvement of genes namely, rhodopsin, RPE65, prominin like 1, and arrestin for Retinitis pigmentosa families.

Lebers Congenital Amaurosis

Leber congenital amaurosis (LCA) and retinitis pigmentosa (RP) are the most severe and most common inherited retinal degenerative (IRD) diseases, respectively. We have performed homozygosity mapping on consanguineous autosomal recessive LCA, RP and cone-rod dystrophy (CRD) families to identify the causative gene. Homozygosity mapping was performed using Affymetrix human mapping array, 250K and 10K GeneChip. Twelve LCA and two arRP and one CRD families were analysed by homozygosity mapping. Direct sequencing of shortlisted candidate gene(s) identified the causative mutations in ten LCA and one arRP families. For one each of LCA, arRP and CRD family, next generation based (NGS) targeted re-sequencing of 184 retinal genes involved in IRD lead to identification of the causative mutation in all three. Targeted re-sequencing was performed in the proband of these three families as the average number of candidate genes within the homozygous blocks were five. In total mutations were identified in eleven LCA, two arRP and one CRD families i.e. in 93% (14/15) of cases studied. Mutations were identified in AIPL1 – 3 families, RPE65- 2 families, RDH12 -2 families and one each in GUCY2D, CRB1, IQCB1 and SPATA7 genes in the LCA and in MERTK and ABCA4 genes in the arRP families and CDHR1 gene in CRD family and 64% of the mutations are novel. The genotype-phenotype correlation was similar to earlier reports and specific to certain genes as well. The results reveal the genetic heterogeneity of the disease and suggest that these approaches are efficient tool for molecular testing in consanguineous families.

Syndromic RP ( Bardet Beidl and Usher Syndrome)

As a part of Indo French collaboration initiative between ICMR and INSERM, the project was conducted with Pr Hélène Dollfus from the Strasbourg university on understanding the molecular epidemiology of BBS in the Indian cohort using a SNP based homozygosity mapping method in 30 small consanguineous Indian pedigrees. The results were further validated in another BBS cohort for recurrent mutations and rapid method of detection. This study has contributed towards the understanding of genetic profile of BBS patients in Indian population by identifying the mutations spectrum of BBS genes in Indian cohort with a potential for diagnostic translation for the patients. Due to many novel genes appended for BBS and the initial work did not include these regions, we are currently focusing on NGS based targeted re sequencing panel based approach, spanning many ciliopathy genes including the known BBS genes. A similar approach is also in progress for Usher syndrome in a sample size of N=100.

Autosomal recessive congenital stationary night blindness

Congenital stationary night blindness (CSNB) is a clinically and genetically heterogeneous retinal disorder which represents rod photoreceptor dysfunction or signal transmission defect from photoreceptors to adjacent bipolar cells. Patients displaying photoreceptor dysfunction show a Riggs-electroretinogram (ERG) while patients with a signal transmission defect show a Schubert–Bornschein ERG. The Schubert–Bornschein is further subdivided into complete or incomplete (ic) CSNB. Only few CSNB cases with Riggs-ERG and only one family with a disease-causing variant in SLC24A1 have been reported. Whole-exome sequencing (WES) in a previously diagnosed icCSNB patient identified a homozygous nonsense variant in SLC24A1. Indeed, re-investigation of the clinical data corrected the diagnosis to Riggs-form of CSNB. Targeted next-generation sequencing (NGS) identified compound heterozygous deletions and a homozygous missense variant in SLC24A1 in two other patients, respectively. ERG abnormalities varied in these three cases but all patients had normal visual acuity, no myopia or nystagmus, unlike in Schubert–Bornschein type of CSNB. This confirms that SLC24A1 defects lead to Riggs type CSNB. In case of unclear clinical characteristics, NGS techniques are helpful to clarify the diagnosis. This study is part of Indo-French collaboration funded by ICMR-INSERM.

Genetic and Functional Characterization of mutations in X-linked Juinile Retinoschisis

The study aimed at establishing a link between the phenotype and genotype based on the molecular mechanism exerted by the mutations. Twenty seven XLRS patients were enrolled and screened for mutations; seven harboured novel mutations. The mutant constructs were genetically engineered and their secretion profiles were studied by in vitro cell culture experiments. Based on the secretory profile, the patients were categorized as either secreted or non-secreted group. Various clinical parameters such as visual acuity, location of schisis, foveal thickness and ERG parameters were compared between the two groups and control. Although the two groups showed severe disease phenotype in comparison with control, there was no significant difference between the two XLRS groups. However, the secreted group exhibited relatively severe disease indications. On the other hand molecular analysis suggests that most of the RS1 mutations result in intracellular retention of retinoschisin. Hence, clinical parameters of patients with non-secreted profile were analyzed which in turn revealed wide variability even within the group. Altogether, our results indicate that disease severity is not merely dependent on secretory profile of the mutations. Thus, we hypothesize that intricate molecular detail such as the precise localization of mutant protein in the cell as well as its ability to assemble into a functionally active oligomer might largely influence disease severity among XLRS patients.

GENETICS OF OPHTHALMIC DISEASES WITH COMPLEX INHERITANCE

Primary Glaucomas ( open and angle closure glaucoma) and Pseudoexfoliation syndrome

Research on molecular Genetics of glaucoma in Indian population was initiated at Sankara Nethralya, as a part of a large epidemiology study titled “ The Chennai Glaucoma study” (2002-2009) with the aim to understand the prevalence and molecular genetics of glaucoma in south Indian population in a sample size of 4758 each for rural (32 contiguous villages around Chennai) and the urban area comprising five random clusters in Chennai city in eligible subjects aged ≥ 40 years. A detailed clinical examination, including glaucoma diagnostic procedure was done at the examination center exclusively dedicated for the project at Sankara Nethralaya. Pedigree ascertainment for genetic studies is performed for subjects with glaucoma. Molecular genetics of both congenital and primary glaucomas (both open angle and angle closure glaucoma) have been the focus of research at the department. Candidate gene analysis for mutations in POAG have shown a frequency of 2-4% of mutations in the population. Genome wide association studies by case control study design has implicated the association of putative genetic loci for PACG and is the first genetic report on PACG genes in the literature. Our Institution was part of the replication study for the ass 11q23.3, 6p21, 3p24 and 5q23 as discovered by deep re controls from nine countries.

Quantitative traits analysis in POAG and Myopia

As part of the Indo US grant, ( Prof Janey Wiggs, Massacuchets eye and ear infirmary) we were able to collect large consanguineous families without any ocular pathology, from south India to map the possible candidate ocular quantitative trait loci (QTLs) for glaucoma. The project also demonstrated the power of consanguineous pedigrees over case control studies in QTL mapping.

Genetic association of variations near/in genes like ATOH7, SIX1/SIX6 complex, CDKN2B, CARD10, and CDC7 were analyzed in POAG and its QTs including vertical cup to disc ratio (VCDR), central corneal thickness (CCT), intra ocular pressure (IOP), and axial length (AL) by case control study in a sample size of 97 POAG cases and 371 controls from South India.A potential interaction was identified for the first time in literature between SNPs near ATOH7— CDC7, SIX6-CARD10, SIX6-CDC7 genes with POAG. SNPs near the genes (ATOH7, SIX6, CDKN2B, CARD10, and CDC7) that did not show individual association with the disease however correlated with increased risk when analyzed for interactions. We also replicated the association of these genes with QTs as observed in other populations. Interactions among genes like ATOH7, SIX6, CDKN2B and CDC7 suggests a putative additive role of the developmental and growth signalling pathways in POAG as hypothesized in many studies. In another study, the association of developmental genes with myopia and its quantitative traits like axial length (AL) refractive error and corneal curvature (CC) was studied. Genotype and haplotype analysis indicated significant association of the haplotype (CTGCGG) bearing the T allele of s36015759 in MFRP gene with decreased axial length values even after multiple correction.

Age Related Macular Degeneration (AMD)

AMD is a highly heritable progressive neurodegenerative disease that leads to loss of central vision through death of photoreceptors. We were a part of AMD gene consortium that included>17,100 advanced AMD cases and >60,000 controls of European and Asian ancestry. The study identified a 32-kb region downstream of Y402H (rs1061170) as risk haplotype for AMD development. Seven new loci (p< 5×10−8) were identified near the genesCOL8A1/FILIP1L,IER3/DDR1, SLC16A8, TGFBR1, RAD51B, ADAMTS9/MR548A2 and B3GALTL were also associated with AMD.

Diabetic Retinopathy (DR)

Candidate gene association studies for diabetic retinopathy are being conducted at the SNONGC department of Genetics and Molecular Biology for the past 15 years; a major part representing the SN-DREAMS (an epidemiology project on understanding the prevalence of DR in rural and urban parts of Tamil Nadu; executed in 3 phases (2003-2010) as given in table below. Currently, we colloborate with Dr Sudha K Iyengar ( DBT Indo US project to foster vision science) to map common and rare susceptibility loci for DR in Indian population.

Fuchs endothelial corneal dystrophy

Fuchs endothelial corneal dystrophy (FECD) is genetically heterogenous degenerative disease of the corneal endothelium with 50% of the cases showing autosomal dominant inheritance and the rest being sporadic. Predominantly a late-onset disease, few early-onset families have also been reported. SLC4A11 is one of the candidate genes for the late-onset FECD. COL8A2 is the candidate gene for the early-onset FECD. Screening SLC4A11 in 45 sporadic late-onset, 4 sporadic early-onset and one autosomal dominant early-onset family identified mutations in three sporadic late-onset cases. These mutations, c.719G4C (p.W240S), c.1519G4A (p.V507I) and c.1304C4T (p.T434I) are novel. Functional studies of these mutants in HEK293 cells revealed defects either in cell surface expression or rate of osmotically driven water flux. Mutation in SLC4A11 was observed in 11% of the cohort studied. No mutations were identified in COL8A2, in either the late-onset cohort or the early-onset family, suggesting genetic heterogeneity in this FECD family.

MOLECULAR GENETIC ANALYSIS IN DEVELOPMENTAL DISORDERS OF THE EYE

Conventional and array based (arffymetrix cytoscan HD array) cytogenetic methods, exon deletion analysis for PAX6 and SOX2 gene by MLPA and targeted resequencing of candidate genes in Illumina platform are being done for understanding the genetics of ocular developmental anomalies in Indian population. Twenty four samples (Microphthalmia (M)-5, Anophthalmia (A)-7,Coloboma-2, M&A-1, microphthalmia and coloboma / other ocular features-9) were initially analyzed using conventional Geimsa Trypsin Geimsa banding of which 4 samples revealed gross chromosomal aberrations (deletions in 3q26.3-28, 11p13 (N=2) and 11q23 regions). Targeted re sequencing of candidate genes showed mutations in CHX10, PAX6, FOXE3, ABCB6 andSHH genes in 6samples. High throughput array based chromosomal analysis revealed aberrations in 4 samples (17q21dup (n=2), 8p11del (n=2)). Overall, genetic alterations in known candidate genes are seen in 50% of the study subjects. Whole exome sequencing was performed in samples that were excluded for mutations in candidate genes are currently being studied

RETINOBLASTOMA

Retinoblastoma (Rb) is the most common primary intraocular cancer of childhood and one of the major causes of childhood cancer death (1%) blindness (5%). Genetic analysis of Rb1 gene has proven effective in early diagnosis and management of the disease.We have also earlier shown that comprehensive screening of retinoblastoma gene (chromosomal/ mutational / methylation analysisand promoter region methylation screening of RB1 gene) is cost effective in carrier detection and disease management for the families with retinoblastoma.NGS-based approaches increase the sensitivity of mutation detection in the RB1 gene, making it fast and cost-effective compared to the conventional tests The study suggested that NGS-based approaches increase the sensitivity of mutation detection in the RB1 gene, making it fast and cost-effective compared to the conventional tests performed in a reflex-testing mode. RB1 gene screening of an 8-month-old female child with bilateral retinoblastoma was accomplished using next generation sequencing. Prenatal testing and carrier testing in mother revealed carrier status of the mother, which was further proceeded for clinical examination in the family members. Prenatal genetic testing of the developing fetus showed positivity for the mutation. The child was monitored for tumour development and treated successfully upon detecting the tumour.Expression analysis of KIF14 and E2F3 mRNA was done and it was found that there is an overexpression of mRNA in Rb tumors.

LEBERS HEREDITARY OPTIC NEUROPATHY

LHON is the most common primary mitochondrial DNA (mtDNA) disorder in the population and it is characterized by preferential loss of retinal ganglion cells, which results in optic nerve degeneration and bilateral severe loss of central vision. We have observed that T14484C mutation and G11778A mutations in `9% and 71% repsectively of the total 90 LHON patients. As a part of multicentric study from India. As a part of the multicentric study, we have reported that the m.11778G>A-related LHON in India coexists with multiple different mtDNA haplogroups. At present we have a Roche Collaborative Research project (Dr Patrick Yu-Wai-Man, NewCastle University) titled “Mitochondrial genome landscape analysis in an Indian cohort of Lebers Hereditary Optic Neuropathy (LHON) patients negative to primary mutation (G3460A, G11778A, and T14484C)” with the aim of the study whole mitochondrial genome in patients negative for the primary mutations.

GENOMIC APPROACHES FOR INDENTIFYING THERAPEUTIC TARGETS IN COMPLEX EYE DISEASES

Whole transcriptome sequencing using RNA-seq to identify the differentially expressed transcripts and novel transcripts (mRNA and miRNA) between drug responders and non-responders in age related diseases like age related macular degeneration and diabetic retinopathy.
