Invitae RCV003513701 SCV004298997 pathogenic Hyper-IgM syndrome type 1 2023-04-22 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that disruption of this splice site is associated with altered splicing resulting in multiple RNA products (PMID: 8550833, 15358621). Disruption of this splice site has been observed in individuals with hyper IgM syndrome (PMID: 7907793, 8550833, 9150729, 15358621). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 4 of the CD40LG gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
