Highlights d Loss of SETD5 impairs brain development and neuronal functions d Setd5 mutant mice exhibit cognitive and sociobehavioral deficits d SETD5 loss leads to an unfavorable chromatin state for RNA elongation and splicing d SETD5 has intrinsic histone methyltransferase activity for H3K36

Body mass index does not allow evaluating differences in lean body mass and FM between athletes and non-athletes. BIA and BIVA can give more reliable details about body composition differences in competitive adolescents and non-competitive, outlining a progressive decline in ECW and increase in ICW without affecting TBW composition of athletes.

Epigenetics is the array of the chromatin modifications that customize in cell-, stage-, or condition-specific manner the information encloses in plain DNA molecules. Increasing evidences suggest the importance of epigenetic mechanisms for development and maintenance of central nervous system. In fact, a large number of newly discovered genetic causes of neurodevelopmental disorders such as intellectual disability, autism spectrum disorders, and many other syndromes are mutations within genes encoding for chromatin remodeling enzymes. Here, we review recent findings on the epigenetic origin of human diseases, with emphasis on disorders that affect development of the nervous system, and discuss novel therapeutic avenues that target epigenetic mechanisms.
