Genes affected

TSPAN12 (HGNC:21641): (tetraspanin 12) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. [provided by RefSeq, Jul 2008]

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. 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: "Benign"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals affected with TSPAN12-related conditions. This variant is present in population databases (rs751690853, gnomAD 0.0009%). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 294 of the TSPAN12 protein (p.Asn294Lys). -
