Invitae | RCV001043081 | SCV001206795 | uncertain significance | Ehlers-Danlos syndrome, musculocontractural type | 2022-03-13 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 134 of the CHST14 protein (p.Arg134Trp). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CHST14-related conditions. ClinVar contains an entry for this variant (Variation ID: 840958). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 | RCV002372776 | SCV002625390 | uncertain significance | Cardiovascular phenotype | 2022-05-16 | criteria provided, single submitter | clinical testing | The p.R134W variant (also known as c.400C>T), located in coding exon 1 of the CHST14 gene, results from a C to T substitution at nucleotide position 400. The arginine at codon 134 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
