CYP4A11

Chr 1

cytochrome P450 family 4 subfamily A member 11

Also known as: CP4Y, CYP4A2, CYP4AII, CYPIVA11

The protein is a cytochrome P450 monooxygenase that catalyzes omega-oxidation of medium-chain fatty acids, particularly lauric acid, and contributes to synthesis of 20-HETE, a signaling molecule that regulates blood pressure. CYP4A11 mutations cause autosomal recessive hypertension and associated cardiovascular complications. The gene shows low constraint against loss-of-function variants (high LOEUF score), consistent with recessive inheritance requiring biallelic mutations for disease manifestation.

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

GOFprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
