Genes affected

TMPRSS15 (HGNC:9490): (transmembrane serine protease 15) This gene encodes an enzyme that converts the pancreatic proenzyme trypsinogen to trypsin, which activates other proenzymes including chymotrypsinogen and procarboxypeptidases. The precursor protein is cleaved into two chains that form a heterodimer linked by a disulfide bond. This protein is a member of the trypsin family of peptidases. Mutations in this gene cause enterokinase deficiency, a malabsorption disorder characterized by diarrhea and failure to thrive. [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: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals affected with TMPRSS15-related conditions. This variant is present in population databases (rs781646198, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 1006 of the TMPRSS15 protein (p.Arg1006Gly). -
