Genes affected

PLCH1 (HGNC:29185): (phospholipase C eta 1) PLCH1 is a member of the PLC-eta family of the phosphoinositide-specific phospholipase C (PLC) superfamily of enzymes that cleave phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) to generate second messengers inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG) (Hwang et al., 2005 [PubMed 15702972]).[supplied by OMIM, Jun 2009]

The c.4365C>G (p.F1455L) alteration is located in exon 23 (coding exon 23) of the PLCH1 gene. This alteration results from a C to G substitution at nucleotide position 4365, causing the phenylalanine (F) at amino acid position 1455 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
