Clinical definition (Orphanet)

A rare oxidative phosphorylation disorder due to nuclear DNA anomalies characterized by onset of slowly proximal lower limb weakness and exercise intolerance in the first decade of life, followed by weakness of neck flexor, shoulder, and distal leg muscles. Facial muscles become involved still later in the disease course. Additional manifestations are restrictive pulmonary function and short stature. Laboratory studies reveal lactic acidemia and increased serum creatine kinase.

How rare: <1 / 1 000 000 — fewer than one in a million. In a city the size of Kolkata, that might mean on the order of fifteen people.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Yes — we know a specific gene responsible (CHCHD10).

GenCC classification: Strong.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

interventional trials for this specific condition

5 interventional trials matched this specific condition name; 2 currently recruiting in our sample. 181 trials are registered for myopathy, the broader category — shown separately because they may or may not enrol this specific subtype.

Data as of 27 July 2026

5 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 87.9th percentile).

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

Recall-expansion terms: CHCHD10

Interventional trials matched via: recall-expansion (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Zero publications but GenCC Strong — literature likely indexed under another name; excluded from neglect count
