    Summary
    This study aimed at identifying genomic regions and genes associated with intramuscular fat content in Duroc pigs using a weighted single-step GWAS. Data from 3912 pigs, of which 3770 animals were genotyped with GeneSeek Porcine 50K Bead chip, were used for the association analysis. We identified 19 genomic regions that each explained > 1% of the additive genetic variance associated with IMF. Notably, a consistent QTL on SSC7 was confirmed, explaining 3.70% of the additive genetic variance, and two genes, BDKRB2 and ATG2B, were highlighted as promising candidates for IMF. Two QTL...
