PLCL2

Chr 3

phospholipase C like 2

Also known as: PLCE2

The PLCL2 protein enables GABA receptor binding and is predicted to regulate inositol trisphosphate signaling around the endoplasmic reticulum. Mutations cause autosomal recessive neurodevelopmental disorders with intellectual disability, seizures, and behavioral abnormalities. This gene is highly constrained against loss-of-function variants (pLI=1.0, LOEUF=0.088), indicating that complete loss of protein function is likely incompatible with normal development.

Clinical SummaryPLCL2
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
