Invitae RCV001207251 SCV001378595 pathogenic 3-methylcrotonyl-CoA carboxylase 2 deficiency 2023-11-22 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 5 of the MCCC2 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 MCCC2 are known to be pathogenic (PMID: 11181649, 22642865). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with clinical features of 3-methylcrotonyl-CoA carboxylase deficiency (PMID: 11181649). This variant is also known as In5ac-1G‚ÜíA. ClinVar contains an entry for this variant (Variation ID: 938097). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
