A Point Mutation at ATP-binding Region of the ALD Gene in a Family With X-linked Adrenoleukodystrophy

Jpn J Hum Genet. 1994 Sep;39(3):345-51. doi: 10.1007/BF01874053.

Abstract

A prenatal diagnosis was performed in a family with X-linked adrenoleukodystrophy (ALD). A fetus was at high risk of suffering the disease by segregation analysis and by very long chain fatty acid-CoA synthetase activity assay. A transition (G to A) at codon 617 of the candidate ALD gene was detected by reverse transcription PCR (RT-PCR) based sequencing of the fetal liver RNA. The mutation was located in highly conserved ATP-binding site in this gene and deduced amino acid transversion R617H was thought to be the cause of ALD in this family.
