Invitae RCV001228226 SCV001400615 likely pathogenic not provided 2022-11-15 criteria provided, single submitter clinical testing 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. This variant disrupts the p.Tyr29 amino acid residue in BEST1. Other variant(s) that disrupt this residue have been observed in individuals with BEST1-related conditions (PMID: 14517959), which suggests that this may be a clinically significant amino acid residue. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BEST1 protein function. ClinVar contains an entry for this variant (Variation ID: 623293). This missense change has been observed in individuals with autosomal dominant childhood-onset Best macular degeneration (PMID: 31570112; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 29 of the BEST1 protein (p.Tyr29Cys).
