Labcorp Genetics (formerly Invitae), Labcorp RCV003116559 SCV003792766 likely pathogenic Mitochondrial hypertrophic cardiomyopathy with lactic acidosis due to MTO1 deficiency 2022-07-17 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with MTO1-related conditions. This variant results in a copy number gain of the genomic region encompassing exon(s) 8-9 of the MTO1 gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be out-of-frame, and may result in an absent or disrupted protein product. Loss-of-function variants in MTO1 are known to be pathogenic (PMID: 22608499, 25058219). 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.
