Genes affected

WFIKKN2 (HGNC:30916): (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 2) The WFIKKN1 protein contains a WAP domain, follistatin domain, immunoglobulin domain, two tandem Kunitz domains, and an NTR domain. This gene encodes a WFIKKN1-related protein which has the same domain organization as the WFIKKN1 protein. The WAP-type, follistatin type, Kunitz-type, and NTR-type protease inhibitory domains may control the action of multiple types of proteases. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 28, 2024

The c.596C>T (p.S199F) alteration is located in exon 2 (coding exon 2) of the WFIKKN2 gene. This alteration results from a C to T substitution at nucleotide position 596, causing the serine (S) at amino acid position 199 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
