This sequence change replaces serine with phenylalanine at codon 156 of the CNGB3 protein (p.Ser156Phe). The serine residue is highly conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is present in population databases (rs139207764, ExAC 0.01%). This variant has been observed in individuals with achromatopsia (PMID: 25616768, 15657609, 28795510). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 427671). This variant has been reported to have insufficient data to determine the effect on CNGB3 protein function (PMID: 26106334). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
