NCIt definition : Human NCSTN wild-type allele is located in the vicinity of 1q23.2 and is approximately
16 kb in length. This allele, which encodes nicastrin protein, plays a role in intramembrane
cleavage of Notch and APP family proteins. Mutation of the gene is associated with
familial acne inversa type 1. Mutagenesis of the gene can caused increased levels
of amyloid-beta secretion and deletions in the gene may inhibit amyloid-beta production.;
