Deletion of the PMP22 gene and hereditary neuropathy with liability to pressure palsies.

Abstract excerpt

Deletion of the 1.5 Mb tract on chromosome 17p11.2-12 that is duplicated in Charcot-Marie-Tooth disease type 1A is commonly associated with hereditary neuropathy with liability to pressure palsies. The deletion, which originates from an unequal meiotic crossover involving two homologous repeats, causes underexpression of the peripheral myelin protein gene PMP22. PMP22 frameshift and non-sense mutations can be...
