APH1A gamma secretase subunit (APH1A) is a gene that encodes a seven-transmembrane-domain protein with an unknown function. The protein is a member of the gamma secretase complex. The complex cleaves membrane proteins such as beta-amyloid precursor proteins and Notch receptors. Missense mutations, silent mutations, and frameshift insertions are observed in cancers such as bone cancer, lung cancer, and skin cancer.

APH1A is altered in 0.37% of all cancers with colon adenocarcinoma, non-small cell lung carcinoma, osteoblastic osteosarcoma, and uterine corpus leiomyosarcoma having the greatest prevalence of alterations [3].
