| Protein Effect | unknown |
| Gene Variant Descriptions | ATRX T899M does not lie within any known functional domains of the Atrx protein (UniProt.org). T899M has been identified in sequencing studies (PMID: 25550361), but has not been biochemically characterized and therefore, its effect on Atrx protein function is unknown (PubMed, Mar 2026). |
