Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MC1R gene is commonly pathogenic or not. These statistics are base on transcript: NM_000002386.4. Only rare variants are included in the table.

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: Receptor for MSH (alpha, beta and gamma) and ACTH. The activity of this receptor is mediated by G proteins which activate adenylate cyclase.
• Disease: DISEASE: Melanoma, cutaneous malignant 5 (CMM5) [MIM:613099]: A malignant neoplasm of melanocytes, arising de novo or from a pre- existing benign nevus, which occurs most often in the skin but also may involve other sites. {ECO:0000269|PubMed:17434924, ECO:0000269|PubMed:19338054}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
