Genes affected

WNT9A (HGNC:12778): (Wnt family member 9A) The WNT gene family consists of structurally related genes that 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 expressed in gastric cancer cell lines. The protein encoded by this gene shows 75% amino acid identity to chicken Wnt14, which has been shown to play a central role in initiating synovial joint formation in the chick limb. This gene is clustered with another family member, WNT3A, in the chromosome 1q42 region. [provided by RefSeq, Jul 2008]

The c.682A>T (p.T228S) alteration is located in exon 4 (coding exon 4) of the WNT9A gene. This alteration results from a A to T substitution at nucleotide position 682, causing the threonine (T) at amino acid position 228 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
