The AIP Mutation Database collects variants (both pathogenic, non-pathogenic and with unknown significance) related to pituitary adenoma predisposition (PAP) and to familial isolated pituitary adenoma (FIPA) syndromes and their clinical information in order to understand better the molecular and clinical details of the disease. Variants are reported according to the GRCh37/hg19 assembly of the human genome and the reference sequence used is the AIP Locus Reference Genomic.
