Clinical Synopsis
 
Phenotypic Series
 

INHERITANCE
- Autosomal dominant
NEUROLOGIC
Peripheral Nervous System
- Distal limb muscle weakness due to peripheral neuropathy
- Distal limb muscle atrophy due to peripheral neuropathy
- 'Steppage' gait
- Foot drop
- Decreased motor nerve conduction velocity (NCV) (less than 38 m/s)
MISCELLANEOUS
- Onset in first or second decade
- Usually begins in feet and legs (peroneal distribution)
- Upper limb involvement may occur later
- Variable severity
- Genetic heterogeneity (see CMT1B, 118200)
- Allelic disorders with overlapping phenotypes include congenital hypomyelinating neuropathy (CHN, 605253) and Dejerine-Sottas syndrome (DSS, 145900)
MOLECULAR BASIS
- Caused by mutation in the early growth response-2 gene (EGR2, 129010.0002)

TEXT

A number sign (#) is used with this entry because this autosomal dominant form of Charcot-Marie-Tooth disease can be caused by mutation in the early growth response gene-2 (EGR2; 129010). Mutations in the same gene have been identified as the cause of autosomal recessive congenital hypomyelinating neuropathy (605253) and Dejerine-Sottas neuropathy (145900).


Description

For a phenotypic description and a discussion of genetic heterogeneity of autosomal dominant Charcot-Marie-Tooth disease type 1, see CMT1B (118200).


Molecular Genetics

Warner et al. (1998) identified heterozygous mutations in the EGR2 gene (129010.0002) in a family with autosomal dominant Charcot-Marie-Tooth disease type 1.


Nomenclature

Street et al. (2003) referred to CMT1 caused by mutation in the EGR2 gene as CMT1D.
