Whole blood RNA was extracted from PAX gene tubes as described in the manufacturer's protocol (QIAGEN PreAnalytiX) Quality and integrity of total RNA was controlled on Agilent Technologies 2100 Bioanalyzer (Agilent Technologies; Waldbronn, Germany). Library construction: Globin mRNA was depleted from total RNA using GLOBINclear Kit, human (ThermoFisher, Invitrogen). Subsequently, a strand-specific RNA sequencing library was generated using NEBNext® Ultra  II Directional RNA Library Prep Kit (New England Biolabs) according to manufacturer's protocols. The library was sequenced on Illumina HiSeq 4000 using HiSeq 3000/4000 SBS Kit (300 cycles) with an average of 40 million reads per RNA sample
