Hello I am a mother of 3 and I have a 5yr old with an undiagnosed genetic syndrome. The genetics doc thinks it is Williams syndrome but she is not missing the elastin gene but there are 1% of children who have WS who arent missing the gene, I just found an article that has done test on children who werent missing the elastin gene and have WS I need to find out what are hypoplastic nail to see if that is a symptom she has.

Summarized question: What is the treatment for Williams syndrome?
