Albinism or congenital nystagmus
Gene: CACNA1F
Initial gene list and info collated by Jonathan Callaway (Wessex Regional Genetics Laboratory) February 2019. Suggested intial gene rating: Green; Comments provided: Comments from OMIM: Aland Island eye disease phenotype includes nystagmus and fundus hypopigmentation. Comments from HGMDpro: 107 variants listed, including numerous LOF variants. Only 2 variants have Aland island eye disease as the reported phenotype (one missense and one 425bp deletion); the majority have night-blindness as the reported phenotype. However, our local clinical expert in ophthalmology suggests including this gene due to the diagnosis of CACNA1F in several patients who pass all the phenotyping tests to exclude retinal disease.Created: 13 Feb 2019, 11:41 a.m.
