Despite having almost all of the prerequisite conditions (heart murmur, lazy eye, left-dominant, hernia, poor motor skills etc.) this was ruled out for me when I was a child due to exhibiting a high-IQ (~130), and I was repeatedly diagnosed with autism, despite being outgoing and high-EQ (and horribly naive!). When I got older I began to develop connective tissue disorders and spasticity, which were incapacitating until I found treatment. I was diagnosed with EDS but that may also have been not-quite-correct, since apparently these issues are also common in WS. Also, it apparently _is_ possible for people with WS to also have higher-than-average IQs. God, life is so frustrating sometimes!
