Rare chromosomal differences found in children with fetal alcohol spectrum disorder

One in four children diagnosed with fetal alcohol spectrum disorder was found to have rare chromosomal differences at considerably higher rates than the general population, according to a study published in Alcohol: Clinical and Experimental Research. Half of those differences were associated with harmful or potentially harmful genetic variations. The study's authors recommend high-resolution genetic testing whenever fetal alcohol spectrum disorder is diagnosed to provide a more complete clinical diagnosis and identify opportunities for improved medical management.
