UBE2E3 and hyperlipidemia: This research aimed to assess the associations of 7 parkin RBR E3 ubiquitin protein ligase (PRKN) and 4 parkin coregulated gene (PACRG) single-nucleotide polymorphisms (SNPs), their haplotypes, gene–gene (G × G) and gene-environment (G × E) interactions with hyperlipidaemia in the Chinese Maonan minority.
