Recessive intellectual disability-motor dysfunction-multiple joint contractures syndrome is a rare, genetic, syndromic intellectual disability disorder characterized by severe intellectual disability, progressive, postnatal, multiple joint contractures and severe motor dysfunction. Patients present arrest and regression of motor function and speech acquisition, as well as contractures which begin in lower limbs and slowly progress in an ascending manner to include spine and neck, resulting in individuals presenting a specific fixed position.
Features include very common findings: Absent speech, Loss of previously acquired skills (developmental regression), Limb joint contracture, and Severe intellectual disability; and common findings: Wide mouth, Macroglossia, Febrile seizure (within the age range of 3 months to 6 years), and Elbow flexion contracture and others. 20 total HPO annotations.
