I’d strongly suspect that these days my Gran would get a diagnosis, and my mum has a lot of traits but probably not diagnosable, her youngest sister is certainly a possibility too. With regards to this also me and my husband have talked about starting our own family, is it possible if we have a son he too would have this? it isn’t sex linked so it would not matter if you had a son or a daughter?
