Genes linked to Thrombocytopenia, X-linked, with or without dyserythropoietic anemia
GATA1: Erythroid transcription factor
It directs erythroid and megakaryocytic differentiation by activating lineage-specific genes and suppressing alternative hematopoietic programs. Germline variants can cause anemia and thrombocytopenia syndromes, while acquired N-terminal mutations are characteristic of transient abnormal myelopoiesis and myeloid leukemia in Down syndrome.
2 disease-causing and 7 uncertain variants in GATA1 are linked to Thrombocytopenia, X-linked, with or without dyserythropoietic anemia.
Known disease-causing variants in Thrombocytopenia, X-linked, with or without dyserythropoietic anemia

|---|---|---|---|
| GATA1 H289Y | 289 | Interaction with CALCOCO1 | Disease-causing (★) |

Frequently asked questions
Which genes are linked to Thrombocytopenia, X-linked, with or without dyserythropoietic anemia?
In CATVariant, Thrombocytopenia, X-linked, with or without dyserythropoietic anemia is linked to 1 analyzed protein: GATA1 (Erythroid transcription factor).
How many genetic variants are linked to Thrombocytopenia, X-linked, with or without dyserythropoietic anemia?
15 variants: 2 are classified as disease-causing (pathogenic or likely pathogenic) in ClinVar and 7 are of uncertain significance or have conflicting reports.
Which uncertain variants in Thrombocytopenia, X-linked, with or without dyserythropoietic anemia look disease-causing?
None of the uncertain variants currently reaches the likely-pathogenic range on computable evidence alone.
About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
