Genes affected

GPR101 (HGNC:14963): (G protein-coupled receptor 101) The protein encoded by this gene is an orphan G protein-coupled receptor of unknown function. The encoded protein is a member of a family of proteins that contain seven transmembrane domains and transduce extracellular signals through heterotrimeric G proteins. [provided by RefSeq, Sep 2011]

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 419 of the GPR101 protein (p.Ala419Ser). This variant is present in population databases (rs781020019, gnomAD 0.001%). This variant has not been reported in the literature in individuals affected with GPR101-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
