PCYOX1 and liver disorder: Multivariate linear regression analysis uncovered that two DEPs (up-regulated in SGA), namely PCYOX1 (related to adipogenesis) and HSP90AA1 (related to lipid metabolism and metabolic-dysfunction-associated steatotic liver disease progression), were independent predictors of the hepatic fat fraction at age 7 (β = 0.634; p = 0.002; R2 = 52% and β = 0.436; p = 0.009; R2 = 24%, respectively).
