RCV001983859 | SCV002278400 | likely pathogenic | Mitochondrial trifunctional protein deficiency; Long chain 3-hydroxyacyl-CoA dehydrogenase deficiency | 2021-09-06 | criteria provided, single submitter | clinical testing | This variant results in the deletion of part of exon 12 (c.1089-2_1089delins17) of the HADHA 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 HADHA are known to be pathogenic (PMID: 7738175, 21103935, 21549624, 22459206). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with HADHA-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. |
