Summer is 6 years old and we live in Australia.We found out Summer is a carrier for Duchenne Muscular Dystrophy when she was 5yrs old. She was very late to sit crawl and walk. She finds it difficult to run and complains a lot of tired legs. I knew there was something different about Summer her whole life, she has had elevated CK levels from 2 yrs old and was finally diagnosed as a carrier of DMD after a full chromosomal microarray was done. I as her mother was tested also am not a carrier.Melissa Brunet
