Invitae RCV000169022 SCV001402877 pathogenic Isovaleryl-CoA dehydrogenase deficiency 2023-08-07 criteria provided, single submitter clinical testing This sequence change affects a splice site in intron 4 of the IVD 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 IVD are known to be pathogenic (PMID: 16602101). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. Disruption of this splice site has been observed in individuals with isovaleric acidemia (PMID: 17576084, 22004070; Invitae). This variant is also known as c.457–3_2CA>GG. ClinVar contains an entry for this variant (Variation ID: 188724). For these reasons, this variant has been classified as Pathogenic.
