Impact List | missense |
Protein Effect | unknown |
Gene Variant Descriptions | CDKN2A A36V lies within ANK repeat 1 of the Cdkn2a protein (UniProt.org). A36V results in decreased suppression of IL3-independent growth in BCR-ABL1-expressing cells in culture (PMID: 34369425), but has not been individually characterized and therefore, its effect on Cdkn2a protein function is unknown. |
