Charcot-Marie-Tooth disease type 1a (CMT 1a) is an autosomal dominant peripheral neuropathy linked to the DNA markers D17S58 and D17S71, located in the pericentromeric region of the chromosome 17p arm. We analyzed an extended 5-generation Belgian family, multiply affected with CMT 1a, for linkage with eight chromosome 17 markers. The results indicated that the CMT 1a mutation is localized in the chromosomal region 17p11.2-p12 between the marker D17S71 and the gene for myosin heavy polypeptide 2 of adult skeletal muscle.
1A型遗传性运动感觉神经病(CMT 1a)是一种常染色体显性周围神经病,与位于17号染色体短臂着丝粒周围区域的DNA标记D17S58和D17S71相关。我们分析了一个五代的比利时大家庭,该家族多名成员患有CMT 1a,对其进行了与8个17号染色体标记的连锁分析。结果表明,CMT 1a突变定位于标记D17S71与成人骨骼肌肌球蛋白重链多肽2基因之间的染色体区域17p11.2 - p12。
