GATA3

Chr 10AD

GATA 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.

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.

GOFIn this study, we identify differential functional consequences of mutation types in GATA3. We present evidence that the most common mutation type results in a protein with elongated C-terminus that displays effects consistent with gain-of-function activity in a cell line model.PMID:27588951
