Invitae RCV001068378 SCV001233487 pathogenic not provided 2020-10-03 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg203*) in the CNGB3 gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs267606739, ExAC 0.01%). This variant has been observed to segregate with achromatopsia in a family and in unrelated individuals affected with this condition, Leber congenital amaurosis or early-onset retinal dystrophy (PMID: 10958649, 25205868, 29186038, 27874104). ClinVar contains an entry for this variant (Variation ID: 5223). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Loss-of-function variants in CNGB3 are known to be pathogenic (PMID: 15657609). For these reasons, this variant has been classified as Pathogenic.
