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.
