Genes affected

TMPRSS4 (HGNC:11878): (transmembrane serine protease 4) This gene encodes a member of the serine protease family. Serine proteases are known to be involved in a variety of biological processes, whose malfunction often leads to human diseases and disorders. This gene was identified as a gene overexpressed in pancreatic carcinoma. The encoded protein is membrane bound with a N-terminal anchor sequence and a glycosylated extracellular region containing the serine protease domain. The protein has been found to promote SARS-CoV-2 entry into host cells. [provided by RefSeq, Aug 2021]

The c.1142A>T (p.D381V) alteration is located in exon 11 (coding exon 11) of the TMPRSS4 gene. This alteration results from a A to T substitution at nucleotide position 1142, causing the aspartic acid (D) at amino acid position 381 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
