RCV002611686 | SCV003508271 | uncertain significance | Argininosuccinate lyase deficiency | 2023-12-11 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 2 of the ASL protein (p.Ala2Asp). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with ASL-related conditions. ClinVar contains an entry for this variant (Variation ID: 2189609). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ASL protein function. 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 | RCV002636844 | SCV003561033 | uncertain significance | Inborn genetic diseases | 2021-06-30 | criteria provided, single submitter | clinical testing | The c.5C>A (p.A2D) alteration is located in exon 2 (coding exon 1) of the ASL gene. This alteration results from a C to A substitution at nucleotide position 5, causing the alanine (A) at amino acid position 2 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
