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.4243C>T (p.P1415S) alteration is located in exon 23 (coding exon 23) of the PLCH1 gene. This alteration results from a C to T substitution at nucleotide position 4243, causing the proline (P) at amino acid position 1415 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
