Genes affected

WFIKKN1 (HGNC:30912): (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 1) This gene encodes a secreted multidomain protein consisting of a signal peptide, a WAP domain, a follistatin domain, an immunoglobulin domain, two tandem Kunitz domains, and an NTR domain. These domains have been implicated frequently in inhibition of various types of proteases, suggesting that the encoded protein may be a multivalent protease inhibitor and may control the action of multiple types of serine proteases as well as metalloproteinases.

The c.445G>A (p.G149S) alteration is located in exon 2 (coding exon 2) of the WFIKKN1 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the glycine (G) at amino acid position 149 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
