Semaphorin-4A is a protein that in humans is encoded by the SEMA4A gene.^[5]^[6]

Function

SEMA4A is a member of the semaphorin family of soluble and transmembrane proteins. Semaphorins are involved in guidance of axonal migration during neuronal development and in immune responses.[supplied by OMIM]^[6]

Clinical significance

A germline variant in SEMA4A (V78M) has been demonstrated to confer risk for colorectal cancer type X.^[7]
