Genes affected

WNT7B (HGNC:12787): (Wnt family member 7B) This gene is a member of the WNT gene family, which 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. Among members of the human WNT family, this gene product is most similar to WNT7A protein. [provided by RefSeq, Oct 2008]

The c.491G>A (p.R164Q) alteration is located in exon 3 (coding exon 3) of the WNT7B gene. This alteration results from a G to A substitution at nucleotide position 491, causing the arginine (R) at amino acid position 164 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
