Genes affected

WFDC2 (HGNC:15939): (WAP four-disulfide core domain 2) This gene encodes a protein that is a member of the WFDC domain family. The WFDC domain, or WAP Signature motif, contains eight cysteines forming four disulfide bonds at the core of the protein, and functions as a protease inhibitor in many family members. This gene is expressed in pulmonary epithelial cells, and was also found to be expressed in some ovarian cancers. The encoded protein is a small secretory protein, which may be involved in sperm maturation. [provided by RefSeq, Jul 2008]

Feb 13, 2024

The c.29C>T (p.A10V) alteration is located in exon 1 (coding exon 1) of the WFDC2 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the alanine (A) at amino acid position 10 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
