Labcorp Genetics (formerly Invitae), Labcorp RCV000555972 SCV000639954 likely pathogenic Epilepsy, X-linked 1, with variable learning disabilities and behavior disorders 2022-08-16 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: 465099). This variant has not been reported in the literature in individuals affected with SYN1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 3 of the SYN1 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 SYN1 are known to be pathogenic (PMID: 14985377, 21441247).
