The mean consensus score for each item was then tallied. The IV fluid rate should be based on the clinical situation. Exome sequencing identifies a novel missense variant in RRM2B associated with autosomal recessive progressive external ophthalmoplegia. Ultrastructural evaluation should be performed routinely in unexplained cholestasis, especially when accompanied by steatosis and hepatocyte hypereosinophilia.59,60, Consensus recommendations for pathology testing. Less frequently, mtDNA depletion can be caused by germline deletions/duplications of mtDNA segments.47 Diagnosis therefore requires quantification of mtDNA content, typically in affected tissue, with identification of a significant decrease below the mean of normal age, gender, and tissue-specific control when normalized to nDNA tissue content.48,49 mtDNA content is not assessed by NGS of the mtDNA genome and must be assayed by a separate quantitative real-time polymerase chain reaction. Sometimes only one organ, tissue, or cell type is affected. Sleep Breath 2013;17:11291135. b. Ann Neurol 2006;59:394398.
