A 4-year old boy is brought to see you (a GP) by his parents because they are concerned about his communication skills

A 4-year old boy is brought to see you (a GP) by his parents because they are concerned about his communication skills and his social skills amongst his peers. His mother tells you that he was born at term and there were no problems at his birth. According to her, he started walking at 12 months old, and there are no other concerns about his motor development. However, he only started speaking in 2 and 3-word sentences in the last 6 months. He still isn’t toilet trained despite mum’s best efforts and struggles to dress himself. He prefers to play alone and struggles to interact with his peers. His height and weight are both between the 50th and 75th centiles. Looking at the child, you can see that he has quite prominent ears and a large head. You decide to refer him to a paediatrician for further tests. Which is the most likely diagnosis?
