Succinate dehydrogenase complex assembly factor 2 (SDHAF2) is a gene that encodes a mitochondrial protein. Missense mutations, synonymous mutations, and frameshift insertions have been observed in cancers such as colon cancer, kidney cancer, and skin cancer.

SDHAF2 is altered in 0.37% of all cancers with breast invasive ductal carcinoma, lung adenocarcinoma, invasive breast carcinoma, colon adenocarcinoma, and breast invasive lobular carcinoma having the greatest prevalence of alterations [3].
