[Genetic Analysis of a Pedigree Affected with X-linked Adrenoleukodystrophy].

OBJECTIVE:To explore the genetic basis for a pedigree affected with X-linked adrenoleukodystrophy presenting as spastic paraplegia of the lower limbs.METHODS:Genomic DNA was extracted from peripheral blood samples of the patient and his mother. Potential variant was detected with a panel for genes associated with spastic paraplegia. Candidate variant was verified by PCR and Sanger sequencing.RESULTS:Both the proband and his mother presented with walking difficulty. A previously known variant, c.623T to A (p.V208E), was identified in the ABCD1 gene mapped on chromosome X in both.CONCLUSION:X-link adrenoleukodystrophy should be taken into account as a possible diagnosis for this pedigree.
