A De Novo GATA1 Mutation Presenting with Recurrent Thrombocytopenia, Pain Syndrome, and Psychiatric Comorbidity: A Case Report

We describe a pediatric case with a novel, de novo GATA1 mutation (c.647G>A; p.Arg216Gln), manifesting not only with classical hematologic abnormalities but also with severe, chronic musculoskeletal pain and psychiatric comorbidity. The patient exhibited recurrent thrombocytopenia, persistent platelet dysfunctions, recurrent mucocutaneous hemorrhages, and developed opioid dependence due to intractable pain, later complicated by psychiatric symptoms. This constellation of features may represent an expanded phenotypic spectrum of GATA1-related disorders, warranting further investigation into potential neuroinflammatory or transcriptional mechanisms.
