| Ambry Genetics | RCV002542605 | SCV003672913 | uncertain significance | Inborn genetic diseases | 2022-12-19 | criteria provided, single submitter | clinical testing | The c.822G>C (p.Q274H) alteration is located in exon 4 (coding exon 3) of the SLX4 gene. This alteration results from a G to C substitution at nucleotide position 822, causing the glutamine (Q) at amino acid position 274 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
| Invitae | RCV003635977 | SCV004533925 | uncertain significance | Fanconi anemia | 2022-12-21 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1337307). This variant has not been reported in the literature in individuals affected with SLX4-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 274 of the SLX4 protein (p.Gln274His). |
