Labcorp Genetics (formerly Invitae), Labcorp RCV001377944 SCV001575400 likely pathogenic T-B+ severe combined immunodeficiency due to JAK3 deficiency 2022-07-06 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 1066836). This variant has not been reported in the literature in individuals affected with JAK3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 18 of the JAK3 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in JAK3 are known to be pathogenic (PMID: 7481768, 11668621).
