Labcorp Genetics (formerly Invitae), Labcorp RCV000705942 SCV000834965 uncertain significance Combined immunodeficiency due to OX40 deficiency 2023-10-22 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 150 of the TNFRSF4 protein (p.Ala150Ser). 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: 581981). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The serine 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.
