Invitae RCV000819219 SCV000959866 pathogenic Mitochondrial trifunctional protein deficiency; Long chain 3-hydroxyacyl-CoA dehydrogenase deficiency 2018-08-06 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 2-20 of the HADHA gene. The 5' boundary is likely confined to intron 1. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. This variant has not been reported in the literature in individuals with HADHA-related disease. A sub-genic deletion of exon 14 has been observed as homozyous in an individual affected with long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency (PMID: 26109258). For these reasons, this variant has been classified as Pathogenic.
