Genes affected

TMPRSS11D (HGNC:24059): (transmembrane serine protease 11D) This gene encodes a trypsin-like serine protease released from the submucosal serous glands onto mucous membrane. It is a type II integral membrane protein and has 29-38% identity in the sequence of the catalytic region with human hepsin, enteropeptidase, acrosin, and mast cell tryptase. The noncatalytic region has little similarity to other known proteins. This protein may play some biological role in the host defense system on the mucous membrane independently of or in cooperation with other substances in airway mucous or bronchial secretions. This protein facilitates entry of viruses into host cells by proteolytically cleaving and activating viral envelope glycoproteins. [provided by RefSeq, Aug 2021]

The c.916G>C (p.A306P) alteration is located in exon 8 (coding exon 8) of the TMPRSS11D gene. This alteration results from a G to C substitution at nucleotide position 916, causing the alanine (A) at amino acid position 306 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
