Comment on list classification: Cataracts part of SLO, which is a very variable condition in presentation.Created: 7 Jun 2016, 12:38 p.m.
Sarah Waller (Manchester Centre for Genomic Medicine)
Cataracts a feature in ~12% of SLOS patients. Lots of publications describing DHCR7 mutations in SLOS but haven't found one with specific mention of cataractsCreated: 25 May 2016, 8:10 a.m.
Phenotypes
Smith-Lemli-Opitz syndrome
Variants in this GENE are reported as part of current diagnostic practice
Ellen McDonagh (Genomics England Curator)
Comment on list classification: Is a confirmed DD gene for SMITH-LEMLI-OPITZ SYNDROME which does include cataracts as a phenotype.Created: 13 May 2016, 1:03 p.m.
Is on the Manchester congenital cataracts gene panel.Created: 29 Apr 2016, 10:46 a.m.
