DefinitionThis section has been translated automatically.

The ELOVLA gene (ELOVL stands for Elongation Of Very Long Chain Fatty Acid Elongase 4) is a protein-coding gene located on chromosome 6q14.1. The gene encodes a membrane-bound protein that belongs to the ELO family, proteins involved in the biosynthesis of fatty acids. Consistent with the expression of the encoded protein in retinal photoreceptor cells, mutations and small deletions in this gene are associated with Stargardt-like macular dystrophy (STGD3) and autosomal dominant Stargardt-like macular dystrophy (ADMD), also known as autosomal dominant atrophic macular degeneration.

The encoded protein is a condensing enzyme that catalyzes the synthesis of very long-chain saturated (VLC-SFA) and polyunsaturated (PUFA) fatty acids, which are involved in numerous biological processes as precursors of membrane lipids and lipid mediators. The enzyme may play an important role in early brain and skin development.
