| Ambry Genetics | RCV002366438 | SCV002659351 | uncertain significance | Inborn genetic diseases | 2024-03-14 | criteria provided, single submitter | clinical testing | The p.D207H variant (also known as c.619G>C), located in coding exon 4 of the ACD gene, results from a G to C substitution at nucleotide position 619. The aspartic acid at codon 207 is replaced by histidine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV003103275 | SCV003495615 | uncertain significance | Dyskeratosis congenita, autosomal dominant 6 | 2022-12-07 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 207 of the ACD protein (p.Asp207His). This variant is present in population databases (rs771131495, gnomAD 0.0009%). 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. 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 ACD protein function. ClinVar contains an entry for this variant (Variation ID: 1752157). This variant has not been reported in the literature in individuals affected with ACD-related conditions. |
