    Finishing the euchromatic sequence of the human genome

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Childhood trauma exposure in substance use disorder patients with and without ADHD

    Background Childhood trauma exposure (CTE) is frequently reported by those with substance use disorders (SUDs). SUDs also frequently co-occur with attention deficit hyperactivity disorder (ADHD). Objective To investigate the role of childhood trauma exposure (CTE) in the presence and the persistence of ADHD in treatment seeking SUD patients. Method Data was derived from the International ADHD in Substance Use Disorder Prevalence (IASP) study. A structured interview was administered to 1274 treatment-seeking SUD patients aged 18 to 65. Results CTE was present in 53.5% of the patients and comorbid adult ADHD in 14.1%. CTE was significantly associated with ADHD: the prevalence of adult ADHD with and without CTE was 19.4% and 8.5% (OR adjusted for age, gender, main substance of abuse, BPD, and ASPD 1.91 [95% CI 1.29–2.81]). CTE was not associated with the severity of adult ADHD or with the persistence of childhood ADHD into adulthood. Conclusions CTE is common in SUD patients and associated with adult ADHD but not with the persistence of childhood ADHD into adulthood. These findings suggest that the increased rate of adult ADHD in SUD patients with CTE is not the consequence of a negative effect of CTE on the persistence of childhood ADHD into adulthood, but a direct expression of the high rate of childhood ADHD in SUD patients with CTE. © 201
