Very long-chain acyl-coenzyme A dehydrogenase deficiency (VLCAD deficiency), a rare autosomal recessive disorder, is characterized by hypoketotic hypoglycemia, cardiomyopathy, liver damage, and myopathy. VLCAD deficiency is caused by defects of ACADVL gene, which encodes VLCAD protein. The aim of this study was to determine the clinical, biochemical, prognosis and mutation spectrum of patients with VLCAD deficiency in mainland China. A total of Six families visited us, four patients (2 boys and 2 girls) were admitted in hospital due to liver dysfunction, hypoglycemia, and positive newborn screen result. The parents of the other two patients (2 girls) visited us for genetic consultation after their children's death. All the six patients had elevated level of serum tetradecenoylcarnitine (C14:1-carnitine), four of them showed decreased free carnitine (C0) level, and three had dicarboxylic aciduria. Eight types of mutations of the ACADVL gene were detected, three of them are novel, including c.563G>A (p.G188D) c.1387G>A (p.G463R) and c.1582_1586del (p.L529Sfs*31). The p.R450H mutation accounts for 9/52 alleles (5/40 in previous study of 20 unrelated patients, and 4/12 in this study) of genetically diagnosed Chinese VLCAD deficiency cases. The four alive patients (Patient 1-4) responded well to diet prevention and drug therapy with stable hepatic dysfunction condition. In conclusion, we describe three novel mutations of the ACADVL gene among six unrelated families with VLCAD deficiency. Moreover, we suggest that the p.R450H may be a potential hotspot mutation in the Chinese population.

Mutation process that restores the wild-type PHENOTYPE in an organism possessing a mutationally altered GENOTYPE. The second "suppressor" mutation may be on a different gene, on the same gene but located at a distance from the site of the primary mutation, or in extrachromosomal genes (EXTRACHROMOSOMAL INHERITANCE).
Conditions which cause proliferation of hemopoietically active tissue or of tissue which has embryonic hemopoietic potential. They all involve dysregulation of multipotent MYELOID PROGENITOR CELLS, most often caused by a mutation in the JAK2 PROTEIN TYROSINE KINASE.
A type of mutation in which a number of NUCLEOTIDES deleted from or inserted into a protein coding sequence is not divisible by three, thereby causing an alteration in the READING FRAMES of the entire coding sequence downstream of the mutation. These mutations may be induced by certain types of MUTAGENS or may occur spontaneously.
