Genes affected
GATAD1 (HGNC:29941): (GATA zinc finger domain containing 1) The protein encoded by this gene contains a zinc finger at the N-terminus, and is thought to bind to a histone modification site that regulates gene expression. Mutations in this gene have been associated with autosomal recessive dilated cardiomyopathy. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2012]

Dilated cardiomyopathy 2B Uncertain:2

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 256 of the GATAD1 protein (p.Thr256Ala). This variant is present in population databases (rs778560008, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with GATAD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 576375). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GATAD1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.766A>G (p.T256A) alteration is located in exon 5 (coding exon 5) of the GATAD1 gene. This alteration results from a A to G substitution at nucleotide position 766, causing the threonine (T) at amino acid position 256 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
