RCV001053686 | SCV001217960 | uncertain significance | Atrioventricular septal defect 5 | 2024-03-16 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 197 of the GATA6 protein (p.Met197Leu). This variant is present in population databases (no rsID available, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with GATA6-related conditions. ClinVar contains an entry for this variant (Variation ID: 849672). 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 GATA6 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 | RCV004031690 | SCV004874459 | uncertain significance | Inborn genetic diseases | 2023-09-22 | criteria provided, single submitter | clinical testing | The c.589A>C (p.M197L) alteration is located in exon 2 (coding exon 1) of the GATA6 gene. This alteration results from a A to C substitution at nucleotide position 589, causing the methionine (M) at amino acid position 197 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
