Alopecia-contractures-dwarfism-intellectual disability syndrome (ACD syndrome) is a form of ectodermal dysplasia syndrome characterized by a short stature of prenatal onset, alopecia, ichthyosis, photophobia, ectrodactyly, seizures, scoliosis, multiple contractures, fusions of various bones (particularly elbows, carpals, metacarpals, and spine), intellectual disability, and facial dysmorphism (microdolichocephaly, madarosis, large ears and long nose). ACD syndrome overlaps with ichthyosis follicularis-alopecia-photophobia syndrome.
Biomarker and diagnostic research for alopecia - contractures - dwarfism - intellectual disability syndrome has been reported in the published literature.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for alopecia - contractures - dwarfism - intellectual disability syndrome.
