Genome-wide meta-analysis identifies 127 open-angle glaucoma loci with consistent effect across ancestries

Primary open-angle glaucoma (POAG), is a heritable common cause of blindness world-wide. To identify risk loci, we conduct a large multi-ethnic meta-analysis of genome-wide association studies on a total of 34,179 cases and 349,321 controls, identifying 44 previously unreported risk loci and confirming 83 loci that were previously known. The majority of loci have broadly consistent effects across European, Asian and African ancestries. Cross-ancestry data improve fine-mapping of causal variants for several loci. Integration of multiple lines of genetic evidence support the functional relevance of the identified POAG risk loci and highlight potential contributions of several genes to POAG pathogenesis, including SVEP1, RERE, VCAM1, ZNF638, CLIC5, SLC2A12, YAP1, MXRA5, and SMAD6. Several drug compounds targeting POAG risk genes may be potential glaucoma therapeutic candidates. Primary open-angle glaucoma (POAG) is highly heritable, yet not well understood from a genetic perspective. Here, the authors perform a meta-analysis of genome-wide association studies in 34,179 POAG cases, identifying 44 previously unreported risk loci and mapping effects across multiple ethnicities

Towards positional cloning of the gene responsible for autosomal dominant retinitis pigmentosa mapped to chromosome 19q13.4

Retinitis pigmentosa (RP) is an inherited group of retinal degenerations that are both clinically and genetically heterogeneous. Autosomal dominant form of RP is caused by mutations in at least 10 loci. The research described in this thesis is focused upon the adRP locus on chromosome 19q13.4 (RP11), which was found by a genome wide linkage analysis on a large British pedigree in our laboratory. At the start of this project RP11 was confined by markers D19S180 and D19S926 to a genetic interval of approximately 11cM and 3 adRP families was linked to RP11 (ADRP5, ADRP29 and RPl907). To further refine this localisation and in order to obtain an estimate of the frequency of RP caused by mutations at this locus 12 more adRP families were genotyped for markers from the disease interval. This led to the identification of two additional RP11 families (ADRP2 and ADRP11) and haplotype analysis in these two families confined the disease region to a 5.8 cM interval between D19S921 and D19S418 and the frequency of the RP11 locus was estimated at approximately 20%. The gene for protein kinase gamma (PRKCG) is localised in the refined RP11 interval and was considered as a positional candidate gene worthy of a thorough investigation. Therefore the genomic organisation of this gene was determined and exon-intron structure was characterised. PRKCG gene was found to consist of 18 exons and a genomic span of at least 16 kb. Following its characterisation this gene was subjected to a thorough mutation analysis. The exons, 5' promoter region, and 3'UTR of this gene was screened in 6 families linked to RP11 locus (ADRP5, ADRP29, ADRP2, RPl907, ADRP24 and a Japanese family). In this analysis a mutation was identified in two adRP families (RP 1907 and ADRP24) and two sporadic RP cases, which were subsequently identified as being founded upon a common ancestor and therefore a single mutation event rather than several independent events. This mutation resulted in the non-conservative replacement of a basic arginine with an uncharged serine at codon 659. Arg659Ser mutation was not found in over 500 normal chromosomes indicating it to be a rare polymorphism. Unfortunately the absence of PRKCG mutations in 7 other RP11 linked pedigrees led to the exclusion of this gene. In order to further refine the RP11 locus novel microsatellite markers were isolated from the distal end of the RP interval using cosmid clones FISH mapped to the region between D19S927 and D19S418, and analysed in the pedigree ADRP2, which presented the distal flanking cross over with D19S418. In this endeavour a total of four microsatellite markers and 5 useful STSs were generated. One of the novel markers, D19S781.2N, recombined with the disease phenotype in ADRP2 and superseded D19S418 as the distal flanking marker. At this stage another group linked three additional families of North American origin to 19ql3.4 and refined the locus proximally replacing D19S921 with D19S572 as the novel proximal flanking marker of the RP11 disease interval. Therefore through the combined genetic data generated both at our laboratory and elsewhere, the RP11 locus was confined between the markers D19S572 (proximal) and D19S781.2N (distal). According to the physical mapping data generated at the Lawrence Livermore National Laboratory (LLNL) Genome Centre the physical distance between these two markers approximate 0.7 Mb. Concurrent to the work described above construction of a YAC contig was also initiated across the RP11 interval, which includes YAC clones from three different YAC libraries. However STS content mapping revealed deletions in several YAC clones that were meant to provide coverage across the RP11 interval, thus indicating a region of instability or a region unclonable in YACs. Therefore PAC clones have replaced YACs as the cloning vector of choice and the current on going work of the project involves the construction of a complete PAC contig across the RP11 interval. Future work will involve the mapping of retinally or brain expressed ESTs, already placed in the 19q13.4 region by the EST mapping consortium (Schuler et al., 1996), to the RP11 critical interval to facilitate the identification of the RP11 gene

Identification and characterization of novel associations in the CASP8/ALS2CR12 region on chromosome 2 with breast cancer risk.

Previous studies have suggested that polymorphisms in CASP8 on chromosome 2 are associated with breast cancer risk. To clarify the role of CASP8 in breast cancer susceptibility, we carried out dense genotyping of this region in the Breast Cancer Association Consortium (BCAC). Single-nucleotide polymorphisms (SNPs) spanning a 1 Mb region around CASP8 were genotyped in 46 450 breast cancer cases and 42 600 controls of European origin from 41 studies participating in the BCAC as part of a custom genotyping array experiment (iCOGS). Missing genotypes and SNPs were imputed and, after quality exclusions, 501 typed and 1232 imputed SNPs were included in logistic regression models adjusting for study and ancestry principal components. The SNPs retained in the final model were investigated further in data from nine genome-wide association studies (GWAS) comprising in total 10 052 case and 12 575 control subjects. The most significant association signal observed in European subjects was for the imputed intronic SNP rs1830298 in ALS2CR12 (telomeric to CASP8), with per allele odds ratio and 95% confidence interval [OR (95% confidence interval, CI)] for the minor allele of 1.05 (1.03-1.07), P = 1 × 10(-5). Three additional independent signals from intronic SNPs were identified, in CASP8 (rs36043647), ALS2CR11 (rs59278883) and CFLAR (rs7558475). The association with rs1830298 was replicated in the imputed results from the combined GWAS (P = 3 × 10(-6)), yielding a combined OR (95% CI) of 1.06 (1.04-1.08), P = 1 × 10(-9). Analyses of gene expression associations in peripheral blood and normal breast tissue indicate that CASP8 might be the target gene, suggesting a mechanism involving apoptosis.Part of this work was supported by the European Community´s Seventh Framework Programme under grant agreement number 223175 (grant number HEALTH-F2-2009-223175) (COGS).

Trinucleotide repeat expansion length as a predictor of the clinical progression of Fuchs' Endothelial Corneal Dystrophy.

PURPOSE:To determine if CTG18.1 TNR expansion length prognosticates the clinical progression of Fuchs' Endothelial Corneal Dystrophy (FECD). METHODS:This was a prospective cohort study. A total of 51 patients with newly diagnosed FECD were recruited and followed-up over a period of 12 years, from November 2004 to April 2016. Baseline clinical measurements included central corneal thickness (CCT), endothelial cell density (ECD) and CTG18.1 TNR expansion length from peripheral leukocytes, with yearly repeat measurements of CCT and ECD. A patient was defined to have experienced significant clinical progression and to have developed Threshold Disease if any of these criteria were fulfilled in either eye: a) CCT increased to >700μm, b) ECD decreased to <700 cells/mm2, or c) underwent keratoplasty for treatment of FECD. RESULTS:Patients were categorized as having at least one allele whose maximum allele length was equal to or greater than 40 repeats (L≥40, n = 22, 43.1%), or having both alleles shorter than 40 repeats (L<40). Threshold Disease rates at the 5-year time point were 87.5% for the L≥40 group and 47.8% for the L<40 group (p = 0.012). This difference narrowed and was no longer statistically significant at the 8-years (92.9% vs 78.9%, p = 0.278) and 10-years (92.9% vs 84.2%, p = 0.426) time points. CONCLUSIONS:L≥40 patients are at greater risk of FECD progression and development of Threshold Disease within the first 5 years following diagnosis

Genome-wide meta-analysis identifies 127 open-angle glaucoma loci with consistent effect across ancestries

Primary open-angle glaucoma (POAG), is a heritable common cause of blindness world-wide. To identify risk loci, we conduct a large multi-ethnic meta-analysis of genome-wide association studies on a total of 34,179 cases and 349,321 controls, identifying 44 previously unreported risk loci and confirming 83 loci that were previously known. The majority of loci have broadly consistent effects across European, Asian and African ancestries. Cross-ancestry data improve fine-mapping of causal variants for several loci. Integration of multiple lines of genetic evidence support the functional relevance of the identified POAG risk loci and highlight potential contributions of several genes to POAG pathogenesis, including SVEP1, RERE, VCAM1, ZNF638, CLIC5, SLC2A12, YAP1, MXRA5, and SMAD6. Several drug compounds targeting POAG risk genes may be potential glaucoma therapeutic candidates. Primary open-angle glaucoma (POAG) is highly heritable, yet not well understood from a genetic perspective. Here, the authors perform a meta-analysis of genome-wide association studies in 34,179 POAG cases, identifying 44 previously unreported risk loci and mapping effects across multiple ethnicities.Peer reviewe

Genome-wide meta-analysis identifies 127 open-angle glaucoma loci with consistent effect across ancestries.

Primary open-angle glaucoma (POAG), is a heritable common cause of blindness world-wide. To identify risk loci, we conduct a large multi-ethnic meta-analysis of genome-wide association studies on a total of 34,179 cases and 349,321 controls, identifying 44 previously unreported risk loci and confirming 83 loci that were previously known. The majority of loci have broadly consistent effects across European, Asian and African ancestries. Cross-ancestry data improve fine-mapping of causal variants for several loci. Integration of multiple lines of genetic evidence support the functional relevance of the identified POAG risk loci and highlight potential contributions of several genes to POAG pathogenesis, including SVEP1, RERE, VCAM1, ZNF638, CLIC5, SLC2A12, YAP1, MXRA5, and SMAD6. Several drug compounds targeting POAG risk genes may be potential glaucoma therapeutic candidates
