Labcorp Genetics (formerly Invitae), Labcorp RCV003037181 SCV003439998 pathogenic Maple syrup urine disease 2023-09-03 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 2136445). This variant has not been reported in the literature in individuals affected with BCKDHB-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ala221Glufs*11) in the BCKDHB gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BCKDHB are known to be pathogenic (PMID: 16786533, 22593002).
