Genes affected

WNT6 (HGNC:12785): (Wnt family member 6) The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. This gene is a member of the WNT gene family. It is overexpressed in cervical cancer cell line and strongly coexpressed with another family member, WNT10A, in colorectal cancer cell line. The gene overexpression may play key roles in carcinogenesis. This gene and the WNT10A gene are clustered in the chromosome 2q35 region. The protein encoded by this gene is 97% identical to the mouse Wnt6 protein at the amino acid level. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.860C>T (p.A287V) alteration is located in exon 4 (coding exon 4) of the WNT6 gene. This alteration results from a C to T substitution at nucleotide position 860, causing the alanine (A) at amino acid position 287 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
