Genes affected

WFDC3 (HGNC:15957): (WAP four-disulfide core domain 3) This gene encodes a member of the WAP-type four-disulfide core (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. The encoded protein contains four WFDC domains. Most WFDC genes are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene belongs to the telomeric cluster. Alternatively spliced transcript variants have been observed but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 16, 2021

The c.422C>A (p.A141E) alteration is located in exon 5 (coding exon 4) of the WFDC3 gene. This alteration results from a C to A substitution at nucleotide position 422, causing the alanine (A) at amino acid position 141 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
