what type of mutation is fragile x syndrome
Fragile X syndrome Fragile X syndrome co-occurs with autism in many cases and is a suspected genetic cause of the autism in these cases.[8][15] This finding has resulted in screening for FMR1 mutation to be considered mandatory in children diagnosed with autism.[8] Of those with fragile X syndrome, prevalence of concurrent autism spectrum disorder (ASD) has been estimated to be between 15 and 60%, with the variation due to differences in diagnostic methods and the high frequency of autistic features in individuals with fragile X syndrome not meeting the DSM criteria for an ASD.[15]
