    This genome-wide association study (GWAS) utilises data from the Western Australian Pregnancy Cohort (Raine) Study for 25-hydroxyvitamin D (25(OH)D) levels measured in blood collected at age 6 years (n=673) and at age 14 years (n=1140). Replication of significantly associated genes from previous GWASs was found for both ages. Genome-wide significant associations were found both at age 6 and 14 with single nucleotide polymorphisms (SNPs) on chromosome 11p15 in PDE3B/CYP2R1 (age 6: rs1007392, P=3.9 × 10(-8); age14: rs11023332, P=2.2 × 10(-10)) and on chromosome 4q13 in GC (age 6: rs17467825, P=4.2 × 10(-9); age14: rs1155563; P=3.9 × 10(-9)). In addition, a novel association was observed at age 6 with SNPs on chromosome 7p15 near NPY (age 6: rs156299, P=1.3 × 10(-6)) that could be of fun

    ABSTRACT: Vitamin D is important for normal skeletal homeostasis, especially in growing children. There are no previous genome-wide association (GWA) studies exploring genetic factors that influence vitamin D metabolism in early childhood. We performed a GWA study on serum 25-hydroxyvitamin D (25(OH)D) and response to supplementation in 761 healthy term-born Finnish 24-month-old children, who participated in a randomized clinical trial comparing effects of 10 μg and 30 μg of daily vitamin D supplementation from age 2 weeks to 24 months. Using the Illumina Infinium Global Screening Array, which has been optimized for imputation, a total of 686085 markers were genotyped across the genome. Serum 25(OH)D was measured at the end of the intervention at 24 months of age. Skeletal parameters ref
