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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.263C>G (p.T88R) alteration is located in exon 2 (coding exon 2) of the WFIKKN1 gene. This alteration results from a C to G substitution at nucleotide position 263, causing the threonine (T) at amino acid position 88 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
