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

Nov 30, 2021

The c.116G>A (p.R39H) alteration is located in exon 1 (coding exon 1) of the WFIKKN2 gene. This alteration results from a G to A substitution at nucleotide position 116, causing the arginine (R) at amino acid position 39 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
