| Invitae | RCV000546535 | SCV000647036 | uncertain significance | RFT1-congenital disorder of glycosylation | 2022-08-04 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 424 of the RFT1 protein (p.Arg424Cys). This variant is present in population databases (rs138803905, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RFT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 469624). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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 | RCV003243188 | SCV003941337 | uncertain significance | Inborn genetic diseases | 2023-04-12 | criteria provided, single submitter | clinical testing | The c.1270C>T (p.R424C) alteration is located in exon 12 (coding exon 12) of the RFT1 gene. This alteration results from a C to T substitution at nucleotide position 1270, causing the arginine (R) at amino acid position 424 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
