Retinal disordersGene: CA4
PMID 15090652: 24 affected individuals from two SA families reported with p.Arg14Trp variant. Another Caucasian family reported in PMID 15563508. This variant is present in 61 hets in gnomad. PMID 15563508 reported another family with p.Arg219Ser. This variant is present in 4 hets in gnomad. PMID 17652713: an individual reported with p.Arg69His. This variant is present in 11 hets in gnomad. Mouse model does not have an eye phenotype. In the absence of other supporting data, the relatively high frequency of the reported variants raises significant concerns about the validity of this gene-disease relationship.

This gene has been demoted from green to amber because there are only 2 published cases (PMID: 15563508; 17652713;15090652).

p.ARG14TRP is too common to a dominant RP mutation. P.ARG219SER is rare but we have ruled this out in ou UK family. Arg69His is in 1 in 3000 SA individuals in gnomAD making it too common. Therefore there is no evidence for CA in IRD.

This gene is on the Manchester Genetic Retinal Degeneration Conditions panel (covers known genes for isolated progessive retinal degeneration, Leber congenital amaurosis, macular dystrophy, achromatopsia, congenital stationary night blindness as well as the two most common causes of syndromic blindess Usher and Bardet-Biedl syndromes and additional syndromes including Joubert, Senior-Loken, and Cohen syndrome.
