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]

Ambry Genetics

Sep 12, 2023

The c.176G>A (p.R59H) alteration is located in exon 2 (coding exon 2) of the PLCH2 gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
