Invitae RCV001213127 SCV001384744 uncertain significance Severe myoclonic epilepsy in infancy 2022-08-23 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 87 of the SNX27 protein (p.Gly87Ala). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with SNX27-related conditions. ClinVar contains an entry for this variant (Variation ID: 943024). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
