Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_021167.5(GATAD1):c.604G>A(p.Ala202Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000798 in 1,591,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A202P) has been classified as Uncertain significance.

Dilated cardiomyopathy 2B Uncertain:3
This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 202 of the GATAD1 protein (p.Ala202Thr). This variant is present in population databases (rs564747350, gnomAD 0.05%). 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: 163499). 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. -

not specified Uncertain:1
The Ala202Thr variant in GATAD1 has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction too ls and conservation analysis do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the Ala202Thr varia nt is uncertain. -
Cardiovascular phenotype Uncertain:1
The c.604G>A (p.A202T) alteration is located in exon 4 (coding exon 4) of the GATAD1 gene. This alteration results from a G to A substitution at nucleotide position 604, causing the alanine (A) at amino acid position 202 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
