Genes affected

WFDC13 (HGNC:16131): (WAP four-disulfide core domain 13) 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]

WFDC10B (HGNC:20479): (WAP four-disulfide core domain 10B) 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. Two alternatively spliced transcript variants have been found for this gene, and they encode distinct isoforms. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 21, 2023

The c.79C>T (p.R27C) alteration is located in exon 1 (coding exon 1) of the WFDC13 gene. This alteration results from a C to T substitution at nucleotide position 79, causing the arginine (R) at amino acid position 27 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
