Labcorp Genetics (formerly Invitae), Labcorp RCV000793166 SCV000932507 uncertain significance Combined immunodeficiency due to OX40 deficiency 2019-06-26 criteria provided, single submitter clinical testing 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. The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in TNFRSF4 cause disease. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with TNFRSF4-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in the last intron (intron 6) of the TNFRSF4 gene. While this is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
