Genes affected

WFDC10A (HGNC:16139): (WAP four-disulfide core domain 10A) 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. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene belongs to the telomeric cluster. [provided by RefSeq, Jul 2008]

WFDC9 (HGNC:20380): (WAP four-disulfide core domain 9) The WAP-type four-disulfide core (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 members of the WFDC domain family. This gene encodes a protein which contains a WFDC domain, and is thus a member of the WFDC domain family. This gene and several other gene family members are clustered at 20q13.12.

Ambry Genetics

Mar 24, 2023

The c.55G>T (p.A19S) alteration is located in exon 1 (coding exon 1) of the WFDC10A gene. This alteration results from a G to T substitution at nucleotide position 55, causing the alanine (A) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
