Invitae RCV000689441 SCV000817092 pathogenic Hyper-IgM syndrome type 1 2023-10-03 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Glu108Thrfs*19) in the CD40LG gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 154 amino acid(s) of the CD40LG protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CD40LG-related conditions. ClinVar contains an entry for this variant (Variation ID: 568935). This variant disrupts a region of the CD40LG protein in which other variant(s) (p.Gly257Asp) have been determined to be pathogenic (PMID: 10366125; Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
