Description

This variant has not been reported in the literature in individuals affected with ADSL-related conditions. 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: 1501479). This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change affects a donor splice site in intron 2 of the ADSL 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 ADSL are known to be pathogenic (PMID: 10888601, 20177786).
