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.811C>T (p.R271C) alteration is located in exon 1 (coding exon 1) of the ANKRD63 gene. This alteration results from a C to T substitution at nucleotide position 811, causing the arginine (R) at amino acid position 271 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
