| Invitae | RCV001214730 | SCV001386429 | uncertain significance | Brown-Vialetto-van Laere syndrome 1 | 2022-08-21 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 401 of the SLC52A3 protein (p.Ala401Ser). 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 SLC52A3-related conditions. ClinVar contains an entry for this variant (Variation ID: 944355). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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 | RCV002348710 | SCV002650560 | uncertain significance | Inborn genetic diseases | 2020-08-14 | criteria provided, single submitter | clinical testing | The p.A401S variant (also known as c.1201G>T), located in coding exon 4 of the SLC52A3 gene, results from a G to T substitution at nucleotide position 1201. The alanine at codon 401 is replaced by serine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. 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. |
