Genes affected

ANKRD63 (HGNC:40027): (ankyrin repeat domain 63)

ANKRD63 links:

PLCB2 (HGNC:9055): (phospholipase C beta 2) The protein encoded by this gene is a phosphodiesterase that catalyzes the hydrolysis of phosphatidylinositol 4,5-bisphosphate to the second messengers inositol 1,4,5-trisphosphate (IP3) and diacylglycerol. The encoded protein is activated by G proteins and has been shown to be involved in the type 2 taste receptor signal transduction pathway. In addition, nuclear factor kappa B can regulate the transcription of this gene, whose protein product is also an important regulator of platelet responses. [provided by RefSeq, Jan 2017]

The c.977G>A (p.G326D) alteration is located in exon 1 (coding exon 1) of the ANKRD63 gene. This alteration results from a G to A substitution at nucleotide position 977, causing the glycine (G) at amino acid position 326 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
