| Gene | KIT |
| Variant | Y870* |
| Impact List | nonsense |
| Protein Effect | unknown |
| Gene Variant Descriptions | KIT Y870* results in a premature truncation of the Kit protein at amino acid 870 of 976 (UniProt.org). Y870* has been identified in sequencing studies (PMID: 35041493), but has not been biochemically characterized and therefore, its effect on Kit protein function is unknown (PubMed, Jul 2025). |
