To read the full abstract: PLoS Genet. 2019 Dec 16;15(12):e1008530.In brief: This genome-wide association study in a cohort of healthy infants shows that, already during the first two years of life, genetic variation in the genes encoding Vitamin D binding protein and Vitamin D 25-hydroxylase correlate with serum 25(OH)D levels and responses to vitamin D supplementation.<p clas...

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...
