Labcorp Genetics (formerly Invitae), Labcorp RCV003620543 SCV004395579 likely pathogenic Mitochondrial trifunctional protein deficiency 2023-05-26 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. This variant has not been reported in the literature in individuals affected with HADHB-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change affects an acceptor splice site in intron 12 of the HADHB 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 HADHB are known to be pathogenic (PMID: 9259266, 12754706).
