Bi-Allelic Splicing Variant, c.153-2A > C in TOMM7 Is Associated With Leigh Syndrome.
Translocase of the outer mitochondrial membrane (TOMM) complex plays an important role in the transport of proteins from the cytoplasm into the mitochondria. TOMM7, one of the subunits of the TOMM complex, modulates its assembly and stability. Bi-allelic disease-causing variants in TOMM7 (MIM* 607980) have been previously reported in two unrelated families with a diverse phenotype of short stature, lipodystrophy, progeria, developmental delay, hypotonia, and skeletal dysplasia. We report a 4-month-old female child significantly affected with neonatal-onset hypotonia, lactic acidosis, optic atrophy, and neuroimaging findings suggestive of Leigh disease with a novel canonical splice variant, c.153-2A > C in TOMM7 (NM_019059.5). Further work done on cDNA of parents revealed the presence of shorter transcripts secondary to aberrant splicing.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
