In Brief: The authors analysed data from the nationwide Child and Adolescent Twin Study in Sweden (CATSS) to estimate the heritability of avoidant restrictive food intake disorder (ARFID) as defined by DSM-5 criteria. Of the 16 951 twin pairs born between 1992 and 2010, 682 (2.0%) children were identified to have ARFID. By modelling shared risk in monozygous compared to dizygous twin pairs, they estimated the heritability of ARFID as 79% (95%CI, 7085).<...

To read the full abstract: Science 2019;365:eaat7693.These authors performed a genome-wide association study on 493 001 participants of European-ancestry from the USA, UK, and Sweden to identify genes associated with sexual orientation. They found multiple loci implicated in same-sex sexual behavior indicating that, like other behavioral traits, non-heterosexual behavior is polygenic.As many as 4% to 10% of US individuals ...
