Genes affected

PLCL1 (HGNC:9063): (phospholipase C like 1 (inactive)) Predicted to enable phospholipase C activity. Predicted to be involved in negative regulation of cold-induced thermogenesis and phosphatidylinositol-mediated signaling. Predicted to act upstream of or within several processes, including gamma-aminobutyric acid signaling pathway; regulation of GABAergic synaptic transmission; and regulation of peptidyl-serine phosphorylation. Predicted to be located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 20, 2021

The c.890G>A (p.R297H) alteration is located in exon 2 (coding exon 2) of the PLCL1 gene. This alteration results from a G to A substitution at nucleotide position 890, causing the arginine (R) at amino acid position 297 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
