Linkage studies between X‐linked adrenoleukodystrophy and a cloned deoxyribonucleic acid fragment (St14), which detects polymorphisms in the distal end of the long arm of the X chromosome (Xq27–28), have shown no recombination in six families. The lod score for these data (and another kindred reported earlier)  is 13.766 at recombination fraction (θ) = 0.0. These data permit assignment of adrenoleukodystrophy carrier status in family members at risk, supplementing the chemical measurement of very‐long‐chain fatty acids.
