For invasive prenatal studies, DNA was extracted from amniocytes using the Sherlock AX DNA isolation kit (A&A Biotechnology, Gdansk, Poland), according to manufacturer’s instructions. Array comparative genomic hybridization (aCGH) in the fetus was performed using the 60K CytoSure Constitutional v3 microarray (Oxford Gene Technology, Oxford, UK).
For further genetic testing, DNA was extracted from the peripheral blood of the newborn and his parents using Gentra Purgene Blood Kit (Qiagen, Germantown, MD, USA). Parental and proband DNA samples were tested for the presence of the CNV deletion using junction-specific PCR with DreamTaq DNA Polymerase (Thermo Scientific, Waltham, MA, USA), followed by Sanger sequencing to map the deletion breakpoints. To determine the parental origin of the detected CNV deletion, trio-based genome sequencing (GS) was performed using NEBNext® Ultra™ II FS DNA Library Prep Kit for Illumina (New England BioLabs, Inc. Ipswich, MA, USA) and paired-end sequenced (2 × 150 bp) on NovaSeq 6000 (Illumina, San Diego, CA, USA). The parental origin of the observed chromosomal abnormality was determined by analyzing the informative single-nucleotide polymorphisms (SNPs) within the deletion region.

Hardy–Weinburg equilibrium was assessed for all genotypes using the χ2 goodness-of-fit test.

DNA was extracted from peripheral blood leukocytes from EDTA whole blood using the Gentra Purgene Blood Kit (QIAGEN Science, Germantown, MD, USA). The genotyping of rs9939609 FTO was performed using 7900HT Fast Real-Time PCR System and predesigned TaqMan SNP Genotyping Assays (Life Technologies/ Thermo Fisher Scientific, Waltham, MA, USA) specified for the SNP. A positive and a negative control were included on each sample tray [24 (link)].

DNA was extracted from peripheral blood using a commercial kit (Gentra Purgene Blood Kit (Qiagen, Gemantown, ML USA). Genotyping tests were developed using Illumina Human Omni 2.5 BeadChip (San Diego, CA, USA). Five genes in the vitamin D pathway were used in this study, VDR, CYP2R1, CYP27B1, CYP24A1 and CG/DBP. The VDR genetic information was extracted from 48,235,320 to 48,298,814 (Location: NC_000012.12) position at chromosome 12; CYP2R1 information was extracted from 1,489,951 to 14,913,874 (location: NC_000011.10) position at chromosome 11; CYP24A1 information was extracted from 52,769,985 to 52,790,516 (location: NC 000,020.11) position at chromosome 20; CYP27B1 information was extracted from 58,156,117 to 58,160,976 (location: NC 000012.12) position at chromosome 12 and DBP information was extracted from 49,133,817 to 49,140,639 (location: NC000019.10) position at chromosome 19. Quality control was carried out in PLINK version 1.07. SNVs were excluded if MAF (minor allele frequency) was less than 1%, imbalance of Hardy–Weinberg equilibrium with P value less than 10−4 and percentage of missing loci more than 1%.

DNA was extracted manually from the buffy coat fractionated from EDTA whole blood using the Gentra Purgene blood kit (QIAGEN Science, MD, USA). DNA samples were quantified using both NanoDrop Spectrophotometer (Thermo Scientific, Wilmington, DE, USA) and PicoGreen DNA methods. Samples (750 ng) were bisulfite converted using the EZ DNA Methylation Kit (Zymo Research, CA, USA). DNA samples were hybridized to the BeadChip arrays by the Genomics Core Facility (GCF) at the Norwegian University of Science and Technology (NTNU), Trondheim, Norway. HumanMethylation450 BeadChips (Illumina, San Diego, CA) were processed according to the manufacturer’s instructions. The BeadChip interrogates 485,000 methylation sites at single-nucleotide resolution. Annotations were done using the UCSC Genome Browser on Human Feb. 2009 (GRCh37/hg19) Assembly. BeadChip batch effects were present, and illustrated using PCA (see Supplementary Fig. 1), although not influenced by BMI since plate location of individuals with high or low BMI was unknown to the laboratory personnel.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
