Genes affected

TMPRSS13 (HGNC:29808): (transmembrane serine protease 13) This gene encodes a member of the type II transmembrane serine protease family. The encoded protein contains a type II transmembrane domain, a receptor class A domain, a scavenger receptor cysteine-rich domain and a protease domain. Transmembrane serine proteases are regulated by protease inhibitors and known to function in development, homeostasis, infection, and tumorigenesis. This protein facilitates entry of viruses into host cells by proteolytically cleaving and activating viral envelope glycoproteins. [provided by RefSeq, Aug 2021]

The c.1253T>C (p.M418T) alteration is located in exon 9 (coding exon 9) of the TMPRSS13 gene. This alteration results from a T to C substitution at nucleotide position 1253, causing the methionine (M) at amino acid position 418 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
