Son of sevenless homolog 1 (SOS1) is a gene that encodes a protein that functions as a guanine nucleotide exchange factor for Ras proteins. The protein regulates RAS proteins by mediating the exchange of GTP to GDP. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

SOS1 is altered in 0.07% of all cancers.

The most common alterations in SOS1 are SOS1 Amplification (0.02%) and SOS1 Loss (0.02%) [3].
