Invitae RCV001376913 SCV001574107 pathogenic not provided 2022-11-15 criteria provided, single submitter clinical testing Disruption of this splice site has been observed in individual(s) with methylmalonic aciduria (PMID: 27167370). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 5 of the MUT 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 MUT are known to be pathogenic (PMID: 15781192). For these reasons, this variant has been classified as 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: 534564).
