Allelic association results of the tag SNPs genotyped in childhood cerebral adrenoleukodystrophy and adrenomyeloneuropathy patients: each black dot represents a tag SNP; -log10P is plotted for each of the 21 tag SNPs; the five CD1 genes are indicated by black boxes; LD between the corresponding tag SNPs is represented by shades of grey as a function of r2 values (black diamond for r2≥0.90, white diamond for r2 = 0). Associated tag SNPs are marked with an asterisk.
