Nine probes were isolated from a human chromosome 1 enriched library and mapped to regions of chromosome 1 using somatic cell hybrid lines. One clone, LR67, which mapped to 1q12 → q23 detected a BglI RFLP. This probe, as well as 4 other known chromosome 1 markers, α‐spectrin, Factor XIIIB, DR10 and DR78, were used for linkage studies in 15 Charcot‐Marie‐Tooth disease (CMT1) families. Close linkage of CMT1 to any of the 5 markers was not indicated. Total lod scores excluded linkage of CMT1 to LR67 and to DR10 at 5 cM or less, to DR78 at 10 cM or less, α‐spectrin at 15 cM or less and Factor XIIIB at 20 cM or less. Possible linkage, however, was shown between LR67 and CMT1 at a distance of 30 cM. Also linkage at a distance of 5 cM was detected between this probe and α‐spectrin.
