Erb-b2 receptor tyrosine kinase 3 (ERBB3) is a gene that encodes a receptor tyrosine kinase in the epidermal growth factor family. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

ERBB3 is altered in 3.16% of all cancers with colorectal adenocarcinoma, breast carcinoma, non-small cell lung carcinoma, uterine corpus neoplasm, and bladder carcinoma having the greatest prevalence of alterations [3].

The most common alterations in ERBB3 are ERBB3 Mutation (3.12%), ERBB3 Amplification (0.30%), ERBB3 V104M (0.17%), ERBB3 E928G (0.13%), and ERBB3 V104L (0.11%) [3].
