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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.271G>A (p.G91S) alteration is located in exon 3 (coding exon 3) of the WFDC2 gene. This alteration results from a G to A substitution at nucleotide position 271, causing the glycine (G) at amino acid position 91 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
