Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the POLE gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Participates in DNA repair and in chromosomal DNA replication.
• Disease: DISEASE: Colorectal cancer 12 (CRCS12) [MIM:615083]: A complex disease characterized by malignant lesions arising from the inner wall of the large intestine (the colon) and the rectum. Genetic alterations are often associated with progression from premalignant lesion (adenoma) to invasive adenocarcinoma. Risk factors for cancer of the colon and rectum include colon polyps, long-standing ulcerative colitis, and genetic family history. CRCS12 is characterized by a high-penetrance predisposition to the development of colorectal adenomas and carcinomas, with a variable tendency to develop multiple and large tumors. Onset is usually before age 40 years. The histologic features of the tumors are unremarkable. {ECO:0000269|PubMed:23263490, ECO:0000269|PubMed:24501277, ECO:0000269|PubMed:25860647, ECO:0000269|PubMed:27573199}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Facial dysmorphism, immunodeficiency, livedo, and short stature (FILS) [MIM:615139]: A syndrome characterized by mild facial dysmorphism, mainly malar hypoplasia, livedo on the skin since birth, and immunodeficiency resulting in recurrent infections. Growth impairment is observed during early childhood and results in variable short stature in adulthood. {ECO:0000269|PubMed:23230001}. Note=The disease is caused by mutations affecting the gene represented in this entry.
