Polymerase (DNA directed), delta 1, catalytic subunit (POLD1) is a gene that encodes a subunit of DNA polymerase delta, a protein complex that plays a critical role in DNA replication and repair. Missense mutations, synonymous mutations, frameshift deletions, and nonsense mutations are observed in cancers such as colon cancer, skin cancer, and stomach cancer.

POLD1 is altered in 2.48% of all cancers with colon adenocarcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, endometrial endometrioid adenocarcinoma, and cutaneous melanoma having the greatest prevalence of alterations [3].

POLD1 GENIE Cases - Top Diseases

The most common alterations in POLD1 are POLD1 Mutation (2.02%), POLD1 Amplification (0.15%), POLD1 X987_splice (0.12%), POLD1 Loss (0.11%), and POLD1 E57del (0.05%) [3].
