Clinical definition (Orphanet)
A rare genetic multiple anomalies/ syndrome characterized by short stature, conductive hearing loss due to bilateral auditory canal atresia, mandibular hypoplasia and multiple skeletal abnormalities, including bilateral humeral hypoplasia, humeroscapular synostosis, delayed pubis rami ossification, central dislocation of the hips, and proximal femora defects, as well as bilateral talipes equinovarus, proximally implanted thumbs and lumbar hyperlordosis. Associated craniofacial dysmorphism includes micro/scaphocephaly, malar hypoplasia, high-arched palate, and simple, dysplastic pinnae with prearicular pits/tags.
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.”
3/6 stages with a signal
No matched interventional trial; the gene is known and literature exists — preclinical or natural-history work may still be the practical next step.

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 (GSC).
GenCC classification: Strong.

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 2026-07-26This 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.
