We found the candidate disease loci via linkage analysis using data from single nucleotide polymorphism genome scans and homozygous truncating mutation <jats:italic>SRD5A3<\/jats:italic> p.W19X, which was previously reported in 3 unrelated children, by exome sequencing.<\/jats:p>\n            <jats:p>Clinical investigations included physical and ocular examinations and blood tests. Severe ocular involvement with retinal bone spicule pigmentation and optic atrophy are the most prominent disabling clinical features of the disease.

They also have atypical ocular findings and variable phenotypes. Our findings widen the spectrum of phenotypes resulting from <jats:italic>SRD5A3<\/jats:italic> mutations and the clinical variability of SRD5A3-CDG, and suggest screening for <jats:italic>SRD5A3<\/jats:italic> mutations in new patients with at least a few of the clinical symptoms of SRD5A3-CDG.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2350-15-10","type":"journal-article","created":{"date-parts":[[2014,1,17]],"date-time":"2014-01-17T00:01:56Z","timestamp":1389916916000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Adult phenotype and further phenotypic variability in SRD5A3-CDG"],"prefix":"10.1186","volume":"15","author":[{"given":"B\u00fclent","family":"Kara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6zgecan","family":"Ayhan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00fclden","family":"G\u00f6k\u00e7ay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nurdan","family":"Ba\u015fbo\u011fao\u011flu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asl\u0131han","family":"Tolun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2014,1,16]]},"reference":[{"key":"1161_CR1","doi-asserted-by":"publisher","first-page":"853","DOI":"10.1007\/s10545-011-9299-3","volume":"34","author":"J Jaeken","year":"2011","unstructured":"Jaeken J: Congenital disorders of glycosylation (CDG): it\u2019s (nearly) all in it.
