ABHD3
Chr 18abhydrolase domain containing 3, phospholipase
Also known as: LABH3
The protein encoded by this gene is a phospholipase that cleaves myristate-containing phosphatidylcholines and other medium-chain phospholipids, contributing to phospholipid remodeling. Biallelic mutations cause autosomal recessive spastic paraplegia with intellectual disability and seizures, typically presenting in early childhood. The gene shows very low constraint against loss-of-function variants (pLI near 0), consistent with recessive inheritance requiring biallelic mutations for disease manifestation.
