Genes affected

WNT8A (HGNC:12788): (Wnt family member 8A) 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, and may be implicated in development of early embryos as well as germ cell tumors. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2014]

The c.718G>A (p.A240T) alteration is located in exon 6 (coding exon 6) of the WNT8A gene. This alteration results from a G to A substitution at nucleotide position 718, causing the alanine (A) at amino acid position 240 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
