N2 - Very-long-chain acyl-CoA dehydrogenase (VLCAD) is one of four straight-chain acyl-CoA dehydrogenase (ACD) enzymes, which are all nuclear encoded mitochondrial flavoproteins catalyzing the initial step in fatty acid beta-oxidation. We have used the very fast, Rapid Amplification of cDNA Ends (RACE) based strategy to obtain the sequence of cDNAs encoding human VLCAD from placenta and fibroblasts. Alignment of the predicted amino acid sequence of human VLCAD with those of the other human ACD enzymes revealed extensive sequence homology. Moreover, human VLCAD and human acyl-CoA oxidase showed extensive sequence homology corroborating the notion that these genes are evolutionarily related. Southern blot analysis of genomic DNA from hybrid cell lines was used to localize the VLCAD gene to human chromosome 17p11.2-p11.13105. Using Northern and Western blot analysis to investigate the tissue specific distribution of VLCAD mRNA and protein in several human tissues we showed that VLCAD is most abundant in heart and skeletal muscle. This agrees well with the fact that cardiac and muscle symptoms are characteristic for patients with VLCAD deficiency. Northern blot analysis and sequencing of cloned PCR amplified VLCAD cDNA from four unrelated patients with VLCAD deficiency showed that VLCAD mRNA was undetectable in one patient and that the other three have mutations in both VLCAD alleles. Western blot analysis of patient fibroblasts showed that the identified mutations result in severely reduced amounts of VLCAD protein. None of the patients harbored identical mutations suggesting that the mutational heterogeneity in VLCAD deficiency is large.
