The Friedreich's ataxia locus (FRDA) has recently been mapped to 9q13-q21 by tight linkage to D9S15 and D9S5 loci. The present lack of recombination between these loci precludes further genetic mapping and suggests that the distances involved are in the megabase range. We have established a 1-Mb map around loci D9S15 (defined by probe MCT112) and D9S5 (defined by probe DR47) and found that they are at most 260 apart. Six rare cutting site clusters were found in a 450-kb segment containing both loci. Three clusters were completely unmethylated in two cell lines tested and might correspond to CpG islands flanking transcribed sequences. Cosmid mapping of a 52-kb region around D9S5 and pulse-field gel electrophoresis analysis showed the presence of three other CpG clusters that were partially or completely methylated. Two of them were present in the cosmid clones available and were associated with sequences conserved in other vertebrate species. The CpG islands and conserved sequences presented here can be used to search for genes defective in Friedreich's ataxia.
