Leucine-rich repeat transmembrane neuronal protein 1 (LRRTM1) is a protein that in humans is encoded by the LRRTM1 gene.[1][2]

LRRTM1 is the first gene linked to increased odds of being left-handed, at least if inherited from the father's side.[3] Possessing one particular variant of the LRRTM1 gene slightly raises the risk of psychotic mental illnesses such as schizophrenia, again only if inherited from the father's side.[3]

As the name implies, its protein product is a transmembrane protein that contains many leucine rich repeats and is present in neurons. It is expressed during the development of specific forebrain structures and shows a variable pattern of maternal downregulation (genomic imprinting).[2]
