CADDS is a rare, genetic, neurometabolic disease characterized by severe intrauterine growth retardation, failure to thrive, profound neonatal hypotonia, severe global development delay, elevated very long chain fatty acids in plasma, and neonatal cholestasis leading to hepatic failure and death. Other features include ocular abnormalities (e.g. blindness and cataracts), sensorineural deafness, seizures, and abnormal brain morphology (notably delayed CNS myelination and ventriculomegaly).
Features include very common findings: Global developmental delay and Cholestasis; and common findings: Inner ear hearing loss (sensorineural hearing impairment), Seizure, Intrauterine growth retardation, and Abnormal brain white matter (abnormal cerebral white matter morphology) and others. 17 total HPO annotations.
