Hi,My 4 year old has been seen by his paediatrician and is being sent for genetic screening as he has multiple birthmarks,my query is that the ones to be concerned about are called cafe au lait spots and his look more like freckles.Is he being thorough checking for neurofibramatosis,he had some speech delay and is awaiting an assessment to help with his fine motor skills. Regards, Anxious mum

Summarized question: Can cafe au lait spots cause speech delay?
