Overview

Collagen, type1, alpha 1 (COL1A1) is a gene that encodes a protein that functions as the pro-alpha 1 chains of type 1 collagen. Fusions, 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 skin cancer.

COL1A1 is altered in 0.36% of all cancers with conventional glioblastoma multiforme, melanoma, anaplastic astrocytoma, dermatofibrosarcoma protuberans, and colorectal adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in COL1A1 are COL1A1-PDGFB Fusion (0.02%), COL1A1 P807A (0.70%), COL1A1 D1347N (0.18%), COL1A1 E354D (0.18%), and COL1A1 P216L (0.13%) [3].
