Clinical definition (Orphanet)
A rare genetic disease characterized by benign circumferential skin creases, mainly on the limbs, due to folding of excess skin. The creases often improve spontaneously in childhood. Patients also exhibit variable degrees of , short stature, cleft palate, and facial dysmorphism (including epicanthal folds, microphthalmia, broad nasal bridge, low-set, posteriorly rotated ears, and microstomia, among others). Variable additional features have been reported, such as , , hearing impairment, strabismus, and urogenital anomalies. Brain imaging may show hypoplastic corpus callosum or mildly dilated ventricles.
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.

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?
Not yet — the cause hasn't been pinned down in GenCC.
No strong gene–disease assertion joined for this Orphanet entity.
Phenotypes (Monarch / HPO)
Not enriched in this build — Monarch phenotype joins were not run for this record.

Where to find support
We do not yet link condition-specific patient organisations. These umbrella groups 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.
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.
"Multiple benign circumferential skin creases on limbs" OR "Circumferential skin creases, Kunze type" OR "Congenital circumferential skin folds" OR "Kunze-Riehm syndrome" OR "CSCSC"
