DeCure for Mitochondrial complex IV deficiency, nuclear type 22

DeCure's autonomous Metabolic AI scientist is researching a drug-repurposing hypothesis for mitochondrial complex IV deficiency, nuclear type 22 — screening already-approved drugs against its 2-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.

The disease map

Disease moduleMitochondrial complex IV deficiency, nuclear type 22 maps to a 2-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for mitochondrial complex iv deficiency, nuclear type 22 is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

What the evidence adds up to

The abstracts provided do not describe any treatment or drug tested in mitochondrial complex IV deficiency, nuclear type 22. The 2010 paper discusses mouse models for nuclear DNA-encoded complex I deficiency, not complex IV, and mentions only that chemical compounds have been tested in patient-derived cell lines for complex I dysfunction, with no results given. The 2001 report describes a single patient with mitochondrial DNA depletion and partial complex II and IV deficiencies plus 3-methylglutaconic aciduria, but no drug or intervention was studied. The 2024 review concerns complex III deficiency and lists no treatments.

No concrete numbers on survival, response rates, or sample sizes for any drug in mitochondrial complex IV deficiency, nuclear type 22 appear in these abstracts. There is no evidence of efficacy for any compound in this specific disease. The abstracts contain no mention of a drug that could be repurposed for this condition.

What is missing is any clinical trial data, any preclinical study in the correct disease model, any patient stratification strategy, and any funding directed specifically at mitochondrial complex IV deficiency, nuclear type 22. Without those, no drug can be proposed.

Mouse models for nuclear DNA‐encoded mitochondrial complex I deficiency

AbstractMitochondrial diseases are a group of heterogeneous pathologies with decreased cellular energy production as a common denominator. Defects in the oxidative phosphorylation (OXPHOS) system, the most frequent one in humans being isolated complex I deficiency (OMIM 252010), underlie this disturbed-energy generation. As biogenesis of OXPHOS complexes is under dual genetic control, with complex II being the sole exception, mutations in both nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) are found. Increasing knowledge is becoming available with respect to the pathophysiology and cellular consequences of OXPHOS dysfunction. This aids the rational design of new treatment strategies. Recently, the first successful treatment trials were carried out in patient-derived cell lines. In these studies chemical compounds were used that target cellular aberrations induced by complex I dysfunction. Before the field of human clinical trials is entered, it is necessary to study the effects of these compounds with respect to toxicity, pharmacokinetics and therapeutic potential in suitable animal models. Here, we discuss two recent mouse models for nDNA-encoded complex I deficiency and their tissue-specific knock-outs.

Mitochondrial DNA Depletion Associated With Partial Complex II and IV Deficiencies and 3-Methylglutaconic Aciduria

AbstractWe report a patient with mitochondrial DNA depletion, partial complex II and IV deficiencies, and 3-methylglutaconic aciduria. Complex II deficiency has not been previously observed in mitochondrial DNA depletion syndromes. The observation of 3-methylglutaconic and 3-methylglutaric acidurias may be a useful indicator of a defect in respiratory chain function caused by mitochondrial DNA depletion.

Pathological variants in nuclear genes causing mitochondrial complex <scp>III</scp> deficiency: <scp>An</scp> update

AbstractMitochondrial disorders are a group of clinically and biochemically heterogeneous genetic diseases within the group of inborn errors of metabolism. Primary mitochondrial diseases are mainly caused by defects in one or several components of the oxidative phosphorylation system (complexes I-V). Within these disorders, those associated with complex III deficiencies are the least common. However, thanks to a deeper knowledge about complex III biogenesis, improved clinical diagnosis and the implementation of next-generation sequencing techniques, the number of pathological variants identified in nuclear genes causing complex III deficiency has expanded significantly. This updated review summarizes the current knowledge concerning the genetic basis of complex III deficiency, and the main clinical features associated with these conditions.
