Labcorp Genetics (formerly Invitae), Labcorp RCV003009090 SCV003298989 uncertain significance Mitochondrial hypertrophic cardiomyopathy with lactic acidosis due to MTO1 deficiency 2022-06-30 criteria provided, single submitter clinical testing This sequence change falls in intron 3 of the MTO1 gene. It does not directly change the encoded amino acid sequence of the MTO1 protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MTO1-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
