| Invitae | RCV001229937 | SCV001402400 | uncertain significance | Charcot-Marie-Tooth disease type 4 | 2022-07-30 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 320 of the PRX protein (p.Ser320Leu). This variant is present in population databases (rs760647416, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with PRX-related conditions. ClinVar contains an entry for this variant (Variation ID: 957028). 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 | RCV002379880 | SCV002695674 | uncertain significance | Inborn genetic diseases | 2022-06-05 | criteria provided, single submitter | clinical testing | The p.S320L variant (also known as c.959C>T), located in coding exon 4 of the PRX gene, results from a C to T substitution at nucleotide position 959. The serine at codon 320 is replaced by leucine, an amino acid with dissimilar 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. |
