Genes affected

PLCH2 (HGNC:29037): (phospholipase C eta 2) PLCH2 is a member of the PLC-eta family of the phosphoinositide-specific phospholipase C (PLC) superfamily of enzymes that cleave PtdIns(4,5) P2 to generate second messengers inositol 1,4,5-trisphosphate and diacylglycerol (Zhou et al., 2005 [PubMed 16107206]).[supplied by OMIM, Jun 2009]

The c.308G>A (p.R103Q) alteration is located in exon 3 (coding exon 3) of the PLCH2 gene. This alteration results from a G to A substitution at nucleotide position 308, causing the arginine (R) at amino acid position 103 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
