While Medium-Chain Acyl-CoA Dehydrogenase (Mcad) stayed unchanged within all experimental groups, Long-Chain Acyl-CoA Dehydrogenase (Lcad) was significantly more expressed in HF animals when compared to C group; Carnitine palmitoyltransferase 1β (Cpt1B) was significantly more expressed in HFF animals compared to C animals. The gene discussed is ACADVL; the disease is hydrops fetalis.
