We previously reported a highly penetrant <i>GATA4</i> p.Gly296Ser mutation in familial, congenital atrial septal defects and pulmonic valve stenosis and showed that mice harboring the orthologous G295S disease-causing mutation display not only atrial septal defects, but also semilunar valve stenosis.

The minor allele C in <i>GATA4</i>: rs17153694 T > C increased the risk of tetralogy of Fallot, whereas minor alleles in <i>TBX1</i>: rs41298006 G>A, <i>FGF10</i>: rs75629618 C>T, <i>FGF10:</i> rs10461755 G>A, <i>FGF10:</i> rs75632187 A>G, and <i>FGF10:</i> rs12518964 G > A were associated with increased risk of single ventricle.

In addition to two polymorphisms of NKX2-5 (rs2277923, rs28936670) variant in the cardiac septal defect, two variants in GATA4 (rs368418329, rs56166237) and one variant in TBX5 (rs6489957) seem to have a role in the pathogenesis of congenital heart disease.
Venous blood samples from 150 congenital heart disease children (including a ventricular septal defect, atrial septal defect, tetralogy of Fallot, and patent ductus arteriosus) and 90 apparently healthy of matched age and sex were studied by polymerase chain reaction followed by direct sequencing in order to study two single-nucleotide variants of NKX2-5 (rs2277923, rs28936670), two single-nucleotide variants of GATA4 (rs368418329, rs56166237) and one single-nucleotide variant TBX5 (rs6489957).

Here, we not only report, for the first time, a c.1309G>A-related CHD, but also report a novel de novo balanced translocation, 46,XY,t(5;7)(qter13;qter11), in the same patient which may have influenced the disease severity.
Rs6601604 was nominally significantly associated with AUD in EA, and 3 SNPs (rs6990313, rs11250159 and rs17153694) showed trend-level significance (P < 0.10) in AA.
To estimate the prevalence and pathogenic potential of GATA4 variants in our CHD cohort, we have screened 285 CHD cases along with 200 controls by Sanger sequencing and identified 9 genetic variants (c.23C>A; p.Ala8Asp, c.25G>A; p.Ala9Thr, c.223G>T; p.Ala75Ser, c.383A>T; p.Glu128Val, c.397A>T; p.Ser133Cys, c.682T>A; p.Trp228Arg, c.1064C>G; p.Thr355Ser, c.1073G>C; p.Ser358Thr, and c.1220C>A; p.Pro407Gln) in 22 unrelated CHD probands (frequency:7.72%).
Among the available genomic studies, the key findings in Africa were variants in GATA4 (P193H), MTHFR 677TT, and MTHFR 1298CC that were associated with atrial septal defect, ventricular septal defect (VSD), Tetralogy of Fallot (TOF), and patent ductus arteriosus phenotypes and 22q.11 deletion, which is associated with TOF.

3 potentially pathogenic variants were identified: c.-77G>A in <i>GATA2</i>, p.Ala343Thr (rs370588269) in <i>GATA4</i>, and p.Pro555Ala (rs146243018) in <i>GATA6</i> Multivariate analyses showed that angina was more frequent in patients carrying sarcomeric and GATA rare variants (55% vs 23.2% in non-carriers of GATA rare variants, OR (95% CI) 7.12 (1.23 to 41.27), p=0.029).
