ESR1
Overview
ESR1 (estrogen receptor 1, also known as ER) is a gene that encodes the estrogen receptor protein. ESR1 plays a role in pathogenesis of cancers such as breast, endometrial, and prostate cancer (PMID: 21779010).
ESR1 is altered in 2.55% of all cancers with breast invasive ductal carcinoma, invasive breast carcinoma, colon adenocarcinoma, lung adenocarcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].
The most common alterations in ESR1 are ESR1 Mutation (2.08%), ESR1 D538G (0.34%), ESR1 Amplification (0.27%), ESR1 Y537S (0.23%), and ESR1 Loss (0.12%) [3].
