Key result
Heterozygous FABP4 SNPs are linked to higher fat content and marbling in Yanbian yellow cattle.
Why the study?
FABP4 is a candidate gene for meat quality traits, but its effects had not been examined in Yanbian yellow cattle.

FABP4 SNPs may aid marker-assisted selection for marbling in Yanbian cattle; leaves open replication across breeds and functional validation.
Observational (n=350)
p-value: p=<0.05
FABP4 SNPs are significantly associated with meat quality traits and lipid metabolism gene expression in Yanbian yellow cattle, suggesting their utility for marker-assisted selection in breeding.
Yin et al. (2020) conducted an observational in Meat quality traits in cattle (n=350). FABP4 single nucleotide polymorphisms (SNPs) vs. Wild-type genotypes was evaluated on Meat quality traits (water, fat, protein content, and marbling) (p=<0.05). Six SNPs in the FABP4 gene were significantly correlated with meat quality traits in Yanbian yellow cattle, with heterozygous individuals at SNP2-6 showing significantly higher fat content and marbling (P < 0.05).
