| Gene Variant Descriptions | ATR K764E does not lie within any known functional domains of the Atr protein (UniProt.org). K764E has been identified in sequencing studies (PMID: 28522871, PMID: 31591497, PMID: 31874108), but has not been biochemically characterized and therefore, its effect on Atr protein function is unknown (PubMed, Mar 2026). |
