The aim of this study was to estimate the prevalence of CSNB in our populations and to study clinical and genetic aspects of the autosomal recessive (AR) form of CSNB. This is a\u00a0retrospective cohort study of Palestinian and Israeli CSNB patients harboring mutations in <jats:italic>TRPM1<\/jats:italic> underwent comprehensive ocular examination. Genetic analysis was performed using homozygosity mapping and sequencing. 161 patients (from 76 families) were recruited for this study, leading to a prevalence of 1:6210 in the vicinity of Jerusalem, much higher than the worldwide prevalence. 61% of the\u00a0families were consanguineous with AR inheritance pattern. Biallelic pathogenic <jats:italic>TRPM1<\/jats:italic> mutations were identified in 36 families (72 patients). Two founder mutations explain the vast majority of cases: a nonsense mutation c.880A&gt;T (p.Lys294*) identified in 22 Palestinian families and a large genomic deletion (36,445\u2009bp) encompassing exons 2\u20137 of <jats:italic>TRPM1<\/jats:italic> present in 13 Ashkenazi Jewish families. Most patients were myopic (with mean BCVA of 0.40 LogMAR) and all had absent rod responses in full field electroretinography. To the best of our knowledge, this is the largest report of a clinical and genetic analysis of patients affected with CSNB due to <jats:italic>TRPM1<\/jats:italic> mutations.<\/jats:p>","DOI":"10.1038\/s41598-019-46811-7","type":"journal-article","created":{"date-parts":[[2019,8,19]],"date-time":"2019-08-19T10:04:06Z","timestamp":1566209046000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["TRPM1 Mutations are the Most Common Cause of Autosomal Recessive Congenital Stationary Night Blindness (CSNB) in the Palestinian and Israeli Populations"],"prefix":"10.1038","volume":"9","author":[{"given":"Alaa","family":"AlTalbishi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lina","family":"Zelinger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3510-1712","authenticated-orcid":false,"given":"Christina","family":"Zeitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Hendler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prasanthi","family":"Namburi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Audo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Sheffer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Yahalom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samer","family":"Khateb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eyal","family":"Banin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dror","family":"Sharon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,8,19]]},"reference":[{"key":"46811_CR1","doi-asserted-by":"publisher","first-page":"58","DOI":"10.1016\/j.preteyeres.2014.09.001","volume":"45","author":"C Zeitz","year":"2015","unstructured":"Zeitz, C., Robson, A.
