Invitae RCV001205085 SCV001376321 likely pathogenic 3-methylglutaconic aciduria type 1 2023-03-10 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: 936309). Disruption of this splice site has been observed in individual(s) with clinical features of 3-methylglutaconic aciduria (Invitae). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change affects a splice site in intron 6 of the AUH 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 AUH are known to be pathogenic (PMID: 12655555, 20882351).
