Genes affected

WFDC6 (HGNC:16164): (WAP four-disulfide core domain 6) 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. Read-through transcription exists between this gene and the upstream SPINLW1 (serine peptidase inhibitor-like, with Kunitz and WAP domains 1) gene. [provided by RefSeq, Nov 2010]

WFDC6 links:

EPPIN-WFDC6 (HGNC:38825): (EPPIN-WFDC6 readthrough) This locus represents naturally occurring read-through transcription between the neighboring SPINLW1 (serine peptidase inhibitor-like, with Kunitz and WAP domains 1) and WFDC6 (WAP four-disulfide core domain 6) genes. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Nov 2010]

The c.121G>A (p.E41K) alteration is located in exon 2 (coding exon 2) of the WFDC6 gene. This alteration results from a G to A substitution at nucleotide position 121, causing the glutamic acid (E) at amino acid position 41 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
