Spectrin, alpha, erythrocytic 1 (SPTA1) is a gene that encodes an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton. Missense mutations, synonymous mutations, nonsense mutations, and frameshift deletions are observed in cancers such as esophageal cancer, genital tract cancer, and endometrial cancer.

SPTA1 is altered in 10.34% of all cancers with cutaneous melanoma, lung adenocarcinoma, colon adenocarcinoma, conventional glioblastoma multiforme, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].
