Genes affected

CRX (HGNC:2383): (cone-rod homeobox) The protein encoded by this gene is a photoreceptor-specific transcription factor which plays a role in the differentiation of photoreceptor cells. This homeodomain protein is necessary for the maintenance of normal cone and rod function. Mutations in this gene are associated with photoreceptor degeneration, Leber congenital amaurosis type III and the autosomal dominant cone-rod dystrophy 2. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some variants has not been determined. [provided by RefSeq, Jul 2008]

The p.Gly122Asp variant in CRX has not been previously reported in individuals with Leber congenital amaurosis but was included on an array of >300 variants for this disease (PMID: 16123401), and has also been identified in >9% of Latino chromosomes and 60 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, this variant meets criteria to be classified as benign for Leber congenital amaurosis. -

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
