MDGA2 (MAM domain containing glycosylphosphatidylinositol anchor 2) is a human gene. It has previously been called MAMDC1.[1] MDGA2 is located on chromosome 14.

The gene has a homologue in rat and mouse, Mdga2,[2] and investigations in rats have found that the gene is expressed in the central and peripheral nervous system in a subpopulation of neurons, e.g., in the basilar pons and cerebral cortex.[3]

There are several variants in the human gene,[4] and a genome-wide association study has pointed to that single-nucleotide polymorphisms in MDGA2 is associated with neuroticism.[5] However, a more recent study has failed to replicate that finding.[6]
