    Large-scale patterns of methylation throughout the genome affect the expression of many autism-related genes and may contribute to the disorder’s development, according to a study published online Friday in Genome Research. The study is among the first to look at genome-wide patterns of methylation in brain cells.

    Blocking a chemical messenger — a much-touted approach to treating fragile X syndrome — is unlikely to completely reverse symptoms of the disorder, according to a provocative new study. The results, published in May in Behavioural Brain Research, show only modest behavioral improvements with the approach.
