Recently, the nuclear-encoded mitochondrial fusion gene <jats:italic>MSTO1<\/jats:italic> (Misato 1) has been implicated in mitochondrial myopathy and ataxia. Here we report on a 30-yr-old man presenting with a maternally inherited NM_018116.3:c.651C&gt;G, p.F217L missense variant as well as a paternally inherited arr[GRCh37] 1q22(155581773_155706887) \u00d7 1 deletion encompassing exons 7\u201314 of <jats:italic>MSTO1<\/jats:italic>. His phenotype included muscle weakness, hypotonia, early motor developmental delay, pectus excavatum, and scoliosis. Testing revealed elevated plasma creatine kinase, and electromyogram results were consistent with longstanding generalized myopathy. These phenotypic features overlap well with previously reported patients harboring biallelic <jats:italic>MSTO1<\/jats:italic> variants. Additionally, our patient presents with dysphagia and restrictive lung disease, not previously reported for <jats:italic>MSTO1<\/jats:italic>-associated disorders. The majority of patients with disease-associated variants in <jats:italic>MSTO1<\/jats:italic> present with biallelic variants suggesting autosomal recessive inheritance; however, one family has been reported with a single variant and presumed autosomal dominant inheritance. The pattern of inheritance we observed is consistent with the majority of previous reports suggesting an autosomal recessive disorder. We add to our knowledge of the syndrome caused by variants in <jats:italic>MSTO1<\/jats:italic> and provide additional evidence supporting autosomal recessive inheritance. We also describe phenotypic features not reported in previous cases, although further research is needed to confirm they are associated with defects in MSTO1.<\/jats:p>","DOI":"10.1101\/mcs.a004309","type":"journal-article","created":{"date-parts":[[2019,10,12]],"date-time":"2019-10-12T00:35:36Z","timestamp":1570840536000},"page":"a004309","source":"Crossref","is-referenced-by-count":8,"title":["Novel biallelic variants in <i>MSTO1<\/i> associated with mitochondrial myopathy"],"prefix":"10.1101","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7222-9985","authenticated-orcid":false,"given":"Laura","family":"Schultz-Rogers","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro","family":"Ferrer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikita R.","family":"Dsouza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael T.","family":"Zimmermann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benn E.","family":"Smith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric W.","family":"Klee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Radhika","family":"Dhamija","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[2019,10,11]]},"reference":[{"key":"2021112506195496000_5.6.a004309.1","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth0410-248"},{"key":"2021112506195496000_5.6.a004309.2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pcbi.1004962"},{"key":"2021112506195496000_5.6.a004309.3","unstructured":"Chinnery PF . 1993.
