Abstract

Inherited retinal diseases (IRDs) are a group of rare Mendelian disorders that often result in progressive vision loss and potentially to complete blindness at the end stage. In this study, we investigated a large cohort of patients with IRDs from Pakistan, the world's fifth most populous country, which is also characterized by distinctive demographic features, such as a high prevalence of consanguinity, endogamy, and a wide variety of ethnic groups. Specifically, we examined a total of 213 unrelated families (722 affected individuals) from three very large geographical regions. We achieved precise molecular diagnosis in 171 pedigrees (80.3%) and detected causative variants in 60 different IRD-associated genes, revealing a mutational landscape that differed substantially from previous data from other European or Asian populations, heavily shaped by endogamy and rare or recurrent founder mutational events. To our knowledge, this work represents the largest genetic study on IRDs within the Pakistani population.

期刊介绍： npj Genomic Medicine is an international, peer-reviewed journal dedicated to publishing the most important scientific advances in all aspects of genomics and its application in the practice of medicine. The journal defines genomic medicine as "diagnosis, prognosis, prevention and/or treatment of disease and disorders of the mind and body, using approaches informed or enabled by knowledge of the genome and the molecules it encodes." Relevant and high-impact papers that encompass studies of individuals, families, or populations are considered for publication. An emphasis will include coupling detailed phenotype and genome sequencing information, both enabled by new technologies and informatics, to delineate the underlying aetiology of disease. Clinical recommendations and/or guidelines of how that data should be used in the clinical management of those patients in the study, and others, are also encouraged.
