Clinical definition (Orphanet)

A rare neuromuscular disease characterized by muscle weakness with focal involvement of the facial, shoulder and limb muscles.

How rare: 1-9 / 100 000 — about one to nine people per hundred thousand.

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?

Probably — there is moderate evidence for LRIF1.

GenCC classification: Moderate.

Phenotypes (Monarch / HPO)

77

Associated phenotypes · MONDO:0001347

  • Upper limb muscle weakness
  • Weakness of facial musculature
  • Mask-like facies
  • Skeletal muscle atrophy
  • Elevated circulating creatine kinase activity

Clinical research

Is a treatment being tested?

40

interventional trials for this specific condition

40 interventional trials matched this specific condition name; 7 currently recruiting in our sample.

Data as of 11 September 2026 · last trial check 28 July 2026

40 interventional trials — more than 77.2% of diseases in the trials denominator have none at all (5501 of 7126; this disease is at the 96.8th percentile).

Recruiting interventional trials

From the matched ClinicalTrials.gov set

40 interventional trials matched after quoted-phrase search and title/condition post-filter.

Observational and natural-history studies

24 observational studies match this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

Where to find support

Condition-specific patient organisations, when Orphanet lists them, are on the disease’s Orphanet page. We also link umbrella groups that support undiagnosed and ultra-rare families.

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.
