ASD indicator?

[Bonosbiatch]

My little boy is 2 years and 3 months old. He has a rare genetic condition which in the vast majority of cases leads to moderate/severe learning disability and an approx 70% chance of ASD.

To cut a long story short, the SEN team working with him suspect he is high functioning. He knows all of his letter sounds (can point to the in any order when I name them) and all of his shapes. There's been very little direct teaching of phonics : 2-3 minutes a day at his request. He is completely non verbal but his understanding is at 40-60 months.

I'm confused. There hasn't been a high functioning case of 48xxyy (his condition) before. I daren't accept that he is in case he somehow regresses. Does this sound weird?

Posted too soon. Is the letter and shape learning a common indicator of ASD? He's obsessed with pylons, turbines and labelling anything going! He's very sociable and makes great eye contact. He is tactile defensive.

Thank you so much for your wise words. My son believes he is talking and uses 'mmmm' with appropriate conversational intonation for everything 😂. I didn't realise how unusual he was until I realised that I was speaking to him as a ks2 child for the majority of the time instead of a 2 year old. I don't like putting it out there with professionals that he's bright, in case they don't believe it due to his condition.
