a The annotations of gene types were obtained from Gencode v33 (https://www.gencodegenes.org/ accessed on 7 July 2022). b Gene types cannot be obtained in Gencode v33 database. NcRNAs d are the further classification of ncRNAs. c GTEx: Genotype-Tissue Expression project. NcRNAs: non-coding RNAs. BMI: Body mass index.
