Compound heterozygous PMP22 deletion mutations causing severe Charcot-Marie-Tooth disease type 1.

Abstract:

:We present a 3⅓-year-old girl with severe Charcot-Marie-Tooth disease type 1 (Dejerine-Sottas disease), who was a compound heterozygote carrying a deletion of the whole peripheral myelin protein 22 (PMP22) and a deletion of exon 5 in the other PMP22 allele. Haplotype analyses and sequence determination revealed a 11.2 kb deletion spanning from intron 4 to 3'-region of PMP22, which was likely generated by nonhomologous end joining. Severely affected patients carrying a PMP22 deletion must be analyzed for the mutations of the other copy of PMP22.
