LINGO2

Chr 9

leucine rich repeat and Ig domain containing 2

Also known as: LERN3, LRRN6C

LINGO2 encodes a membrane protein that positively regulates synapse assembly and is active at glutamatergic synapses and synaptic membranes. The gene is highly constrained against loss-of-function variants (pLI=0.86, LOEUF=0.42), suggesting that mutations likely cause significant developmental or neurological phenotypes. However, specific disease associations and inheritance patterns for LINGO2 have not been established in the current literature.
