RCV000687484 | SCV000815053 | uncertain significance | Dyskeratosis congenita, autosomal dominant 6 | 2023-08-09 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 333 of the ACD protein (p.Gln333His). This variant is present in population databases (rs776468683, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ACD-related conditions. ClinVar contains an entry for this variant (Variation ID: 567408). 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 | RCV002386172 | SCV002689672 | uncertain significance | Inborn genetic diseases | 2023-10-06 | criteria provided, single submitter | clinical testing | The p.Q333H variant (also known as c.999G>C), located in coding exon 8 of the ACD gene, results from a G to C substitution at nucleotide position 999. The glutamine at codon 333 is replaced by histidine, an amino acid with highly 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. |
