To read the full abstract: Nat Commun 2019;10:343This paper reports many loci associated with chronotype (i.e. being a ‘morning person’ or ‘evening person’) in a genome-wide association study (GWAS) of 697, 828 participants from the UK Biobank and 23andMe cohorts. The link between chronotype and sleep timing and quality is well known. It was therefore interestin...

Abstract: JCI Insight. 2019; Apr 4;4(7).In brief: This study describes a novel autosomal dominant form of primary osteoporosis caused by SGMS2 mutations in six families. A recurrent mutation p.Arg50* led to primary osteoporosis in four families, whereas missense mutations p.Ile62Ser and p.Met64Arg caused a much more severe bone phenotype with spondylometaphyseal d...
