RCV000779382 | SCV000915988 | likely pathogenic | Acyl-CoA dehydrogenase 9 deficiency | 2018-10-24 | criteria provided, single submitter | clinical testing | The ACAD9 c.359delT (p.Phe120SerfsTer9) variant is a frameshift variant that is predicted to result in premature termination of the protein. This variant has not been reported in the literature; however an equivalent variant, c.358delT (p.Phe120SerfsTer9) has been reported in at least five studies and is found in a compound heterozygous state in a total of three individuals with ACAD9 deficiency (Lee et al. 2014; Collet et al. 2015; Schiff et al. 2015; Fragaki et al. 2017; Repp et al. 2018). Control data are unavailable for the p.Phe120SerfsTer9 variant, which is reported at a frequency of 0.000527 in the Latino population of the Genome Aggregation Database. Mitochondrial respiratory chain complex I activity was reduced in patient-derived muscle and heart tissue (Collet et al. 2015; Schiff et al. 2015; Fragaki et al. 2017). Based on the evidence, the p.Phe120SerfsTer9 variant is classified as likely pathogenic for ACAD9 deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. |

RCV000813209 | SCV000953554 | pathogenic | not provided | 2024-12-20 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Phe120Serfs*9) in the ACAD9 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ACAD9 are known to be pathogenic (PMID: 25721401). This variant is present in population databases (rs746304569, gnomAD 0.05%). This premature translational stop signal has been observed in individuals with mitochondrial complex I deficiency (PMID: 25721401, 26669660, 28529009). This variant is also known as c.358delT. ClinVar contains an entry for this variant (Variation ID: 242524). For these reasons, this variant has been classified as Pathogenic. |

RCV002282085 | SCV002571761 | pathogenic | Mitochondrial complex I deficiency | 2024-01-11 | criteria provided, single submitter | clinical testing | Variant summary: ACAD9 c.359delT (p.Phe120SerfsX9) results in a premature termination codon, predicted to cause absence of the protein due to nonsense mediated decay, which is a commonly known mechanism for disease. The variant allele was found at a frequency of 0.0001 in 247292 control chromosomes (gnomAD). This frequency is not higher than expected for a pathogenic variant in ACAD9 causing Mitochondrial Complex I Deficiency, Nuclear Type 20 (0.0001 vs 0.0011). c.359delT (also known as c.358delT) has been reported in the literature in individuals affected with Mitochondrial Complex I Deficiency and the variant segregated with disease (examples: Collet_2016, Fragaki_2017, Schiff_2015, and Barbosa-Gouveia_2021). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 34440436, 26669660, 28529009, 34023438, 25721401). Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic (n=5) and likely pathogenic (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. |
