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]

This sequence change creates a premature translational stop signal (p.Arg857*) in the TMPRSS15 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TMPRSS15 are known to be pathogenic (PMID: 11719902). This variant is present in population databases (rs121908059, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with congenital enteropeptidase deficiency (PMID: 11719902). ClinVar contains an entry for this variant (Variation ID: 4165). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
