RCV001992648 | SCV002223010 | uncertain significance | Combined immunodeficiency due to OX40 deficiency | 2023-12-05 | 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 7 of the TNFRSF4 protein (p.Arg7Trp). 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 TNFRSF4-related conditions. ClinVar contains an entry for this variant (Variation ID: 1445673). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Not Available"; Align-GVGD: "Not Available". The tryptophan 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 | RCV004043729 | SCV003561658 | uncertain significance | not specified | 2021-06-18 | criteria provided, single submitter | clinical testing | The c.19C>T (p.R7W) alteration is located in exon 1 (coding exon 1) of the TNFRSF4 gene. This alteration results from a C to T substitution at nucleotide position 19, causing the arginine (R) at amino acid position 7 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
