PHOX2B
Overview
Paired-like homeobox 2b (PHOX2B) is a gene that encodes a protein that functions as a transcription factor involved in the development of norandrenergic neuron populations and determination of neurotransmitter pheynotype. Missense mutations, silent mutations, nonsense mutations, frameshift deletions, and frameshift insertions are observed in cancers such as skin cancer, pleural cancer, and colon cancer.
PHOX2B is altered in 0.93% of all cancers with colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, endometrial endometrioid adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].
The most common alterations in PHOX2B are PHOX2B Loss (0.13%), PHOX2B Amplification (0.07%), PHOX2B A256_A260del (0.08%), PHOX2B A254_A260del (0.06%), and PHOX2B T205P (1.00%) [3].
