Abstract

fetched live from OpenAlex

Abstract Coenzyme Q 10/ COQ 10 , an essential cofactor in the electron‐transport chain is involved in ATP production. Primary COQ 10 deficiency is clinically and genetically a heterogeneous group of mitochondrial disorders caused by defects in the COQ 10 synthesis pathway. Its mode of inheritance is autosomal recessive and it is characterized by metabolic abnormalities and multisystem involvement including neurological features. Mutations in 10 genes have been identified concerning this group of diseases, so far. Among those, variants of the COQ7 gene are very rare and confined to three patients with Asian ancestry. Here, we present the clinical features and results of whole‐exome sequencing (WES) of three Iranian unrelated families affected by primary COQ 10 deficiency. Three homozygous variants in COQ2 , COQ4 , and COQ7 genes were identified. Candidate variants of the COQ2 and COQ4 genes were novel and associated with the cerebellar signs and multisystem involvement, whereas, the known variant in COQ7 was associated with a mild phenotype that was initially diagnosed as hereditary spastic paraplegia (HSP). This variant has already been reported in a Canadian girl with similar presentations that also originated from Iran suggesting both patients may share a common ancestor. Due to extensive heterogeneity in this group of disorders, and overlap with other mitochondrial/neurological disorders, WES may be helpful to distinguish primary coenzyme Q 10 deficiency from other similar conditions. Given that some features of primary coenzyme Q 10 deficiency may improve with exogenous COQ 10 , early diagnosis is very important.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
