We aimed to test for replication and transferability of our European-centric results in 401 RP cases of British Bangladeshi and Pakistani ancestry from the Genes & Health cohort30 (n = 40,532), and observed directionally concordant results (rs11748327; OR = 1.16, 95%-CI = 0.99–1.37, p-value = 0.06; IRX1) for one of the two strongest loci, while for the second one, rs7090046 (ADRA2A), the lead variant or suitable genetic proxies were not available. The gene discussed is IRX1; the disease is retinitis pigmentosa 1.
