Genes affected

GATA3 (HGNC:4172): (GATA binding protein 3) This gene encodes a protein which belongs to the GATA family of transcription factors. The protein contains two GATA-type zinc fingers and is an important regulator of T-cell development and plays an important role in endothelial cell biology. Defects in this gene are the cause of hypoparathyroidism with sensorineural deafness and renal dysplasia. [provided by RefSeq, Nov 2009]

GATA3 Gene-Disease associations (from GenCC):

• hypoparathyroidism-deafness-renal disease syndrome

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 7.8, offset of 8, new splice context is: atctttgtttacattaacAGacc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-8073738-G-C is Pathogenic according to our data. Variant chr10-8073738-G-C is described in ClinVar as Pathogenic. ClinVar VariationId is 430696.Status of the report is criteria_provided_single_submitter, 1 stars.
