摘要: The crossover breakpoints for Charcot-Marie-Tooth disease type 1A (CMT1A) and hereditary neuropathy with liability to pressure palsies (HNPP) are located in the CMT1A-REP repeat flanking a 1.5-Mb region of chromosome 17p11.2–12. precise locations heterogeneous, we analyzed relative frequency distribution 33 unrelated Japanese CMT1A 3 HNPP families. was divided into five regions, A, B, C, D E, based on restriction site differences between proximal distal repeats. within patients 3% 78% B/C 19% D, which is similar that Caucasian patients. This result also indicates an 8-kb defined by recombinational hotspot
