GATA3
Chr 10ADGATA binding protein 3
Also known as: HDR, HDRS
The GATA3 transcription factor binds to specific DNA sequences to regulate T-cell development and differentiation, particularly in Th2 immune responses, and also functions in endothelial cell biology. Loss-of-function mutations cause autosomal dominant hypoparathyroidism, sensorineural deafness, and renal dysplasia (HDR syndrome). The gene is highly intolerant to loss-of-function variants, consistent with haploinsufficiency as the underlying disease mechanism.
Definitive — sufficient evidence for diagnostic panels
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (loss-of-function, dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to loss-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Literature Evidence
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
