We recommend early multidisciplinary input from the following health professionals:
• Physiotherapy: management of hypotonia, observation for kyphosis, scoliosis, torticollis, spasticity and dystonia
• Speech and language therapy: Encourage language development.
• Paediatrics: developmental assessments, observation for insulin resistance/acanthosis, weight gain or weight loss, hirsutism (dermatology referral may be needed), seizures and other neurological complications, consider screening for immunodeficiency (including lymphocyte subsets and vaccine antibody titres).
• Ophthalmology: observation for strabismus and cataracts.
• Clinical genetics: genetic counselling.
