Genes affected

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.3168G>T (p.Q1056H) alteration is located in exon 29 (coding exon 29) of the PLCB2 gene. This alteration results from a G to T substitution at nucleotide position 3168, causing the glutamine (Q) at amino acid position 1056 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
