Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 2P and 16B. PP3_ModerateBP6_Very_StrongBS1BS2

The NM_002772.3(TMPRSS15):c.2905G>A(p.Gly969Arg) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.000284 in 1,613,248 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G969E) has been classified as Uncertain significance.

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]
