|a OBJECTIVE: X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder characterized by progressive demyelination of the central nervous system, adrenal cortex insufficiency and accumulation of saturated very long chain fatty acids (VLCFAs) in tissues and body fluids due to the impaired beta-oxidation in peroxisomes. X-ALD shows a wide range of phenotypic variation. Childhood cerebral form (CCER) is the most common phenotype with severe neurological symptoms and often the average interval from onset to total disability or death is 3 years. So far no effective treatment is available for the underlying defect. Screening for carriers of mutated relevant gene and prenatal diagnosis are very important for the prevention of the disease. In this study, the authors explored the method of carrier screening and prenatal diagnosis of X-ALD

|
|a METHODS: The plasma VLCFAs levels of 83 suspected carriers for ALD were determined by using GC/MS and ABCD1 gene mutational analysis was performed in 31 of them. Amniocentesis was performed in 9 suspected carriers for ALD during 18 - 30 gestational weeks. The VLCFAs level of cultured amniocytes was tested with GC/MS. ABCD1 gene mutational analysis was performed on two cases (one was a male and the other a female) whose VLCFAs levels of amniocytes were found elevated. The plasma VLCFAs levels were measured in five of the nine prenatally diagnosed children when they were 1 day to 3.5 years old

|
|
|a RESULTS: Fifty-one of 83 suspected carriers had high plasma VLCFAs levels; 29 of 31 suspected carriers showed ABCD1 gene mutation. Among the nine fetuses, four were males and five were females. The VLCFAs levels of the cultured amniocytes were high in two cases, one was female and the other a male. ABCD1 gene mutational analysis of these two cases showed a 871G > A (E291K) mutation and a 726G > A (W242X) mutation, respectively, which confirmed the biochemical result. The VLCFAs levels were normal in the rest of cases and five of them were confirmed by postnatal plasma VLCFAs assay

|
|a CONCLUSION: The carrier screening and prenatal diagnosis are very important for prevention of the X-ALD. Only the combined use of plasma VLCFAs level analysis and ABCD1 gene mutational analysis could detect X-ALD carriers correctly. ABCD1 gene mutational analysis and postnatal plasma VLCFAs level test verified that amniocytes VLCFAs level analysis is a reliable prenatal diagnostic method for this disease
