GATA2 deficiency with susceptibility to MDS/AML: genes and variants

Genes linked to GATA2 deficiency with susceptibility to MDS/AML

• GATA2: Endothelial transcription factor GATA-2

  It maintains hematopoietic stem and progenitor cells and directs development of monocytes, dendritic cells, NK cells, and other blood lineages. Haploinsufficiency causes GATA2 deficiency with immunodeficiency, cytopenias, and high risk of myelodysplastic syndrome or AML.

  32 disease-causing and 18 uncertain variants in GATA2 are linked to GATA2 deficiency with susceptibility to MDS/AML.

Where GATA2 deficiency with susceptibility to MDS/AML variants cluster

• GATA2 GATA-type 2 (positions 349–373): 19 of 32 disease-causing changes, 11.4× more than its size predicts.

Known disease-causing variants in GATA2 deficiency with susceptibility to MDS/AML

Uncertain variants in GATA2 deficiency with susceptibility to MDS/AML that look disease-causing

Which prediction tools work for GATA2 deficiency with susceptibility to MDS/AML

How often each tool ranks a disease-causing variant above a harmless one (AUROC × 100).

• CATVariant: 100 out of 100 (learned from overlapping clinical labels, so this is optimistic)
• SIFT: 99 out of 100
• PolyPhen-2: 99 out of 100 (learned from overlapping clinical labels, so this is optimistic)

Same protein, different disease

• Monocytopenia with susceptibility to infections is also caused by GATA2 variants; they fall in the same places as the GATA2 deficiency with susceptibility to MDS/AML variants (12 disease-causing).

Frequently asked questions

Which genes are linked to GATA2 deficiency with susceptibility to MDS/AML?

In CATVariant, GATA2 deficiency with susceptibility to MDS/AML is linked to 1 analyzed protein: GATA2 (Endothelial transcription factor GATA-2).

How many genetic variants are linked to GATA2 deficiency with susceptibility to MDS/AML?

61 variants: 32 are classified as disease-causing (pathogenic or likely pathogenic) in ClinVar and 18 are of uncertain significance or have conflicting reports.

Which uncertain variants in GATA2 deficiency with susceptibility to MDS/AML look disease-causing?

3 uncertain variants reach the likely-pathogenic range of the ACMG/AMP points scale on computable evidence, for example GATA2 M388V, GATA2 W360R and GATA2 R361H. These are leads for expert review, not diagnoses.

Which variant effect predictor works best for GATA2 deficiency with susceptibility to MDS/AML?

Among tools not trained on clinical labels, SIFT separates this disease's known disease-causing variants from harmless ones best (AUROC 0.99, based on 32 disease-causing and 11 harmless variants).

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.
