A LRSAM1 mutation links Charcot-Marie-Tooth type 2 to Parkinson's disease.

LRSAM1 mutations have been found in recessive and dominant forms of Charcot-Marie-Tooth disease. Within one generation of the original Dutch family in which the dominant LRSAM1 mutation was identified, three of the five affected family members have developed Parkinson's disease between ages 50 and 65 years, many years after neuropathy onset. We speculate that this late-onset parkinsonism is par...

Factors Affecting Phenotype Variability in a Family with CMT2B: Gender and LRSAM1 Genotype

Charcot-Marie-Tooth disease type 2 (CMT2) is an autosomal dominant axonal neuropathy caused by mutations in various genes. The subtype CMT2B results from missense mutations in RAB7A, member RAS oncogene family gene, whereas missense mutations in the Leucine-rich repeat and sterile alpha motif-containing protein 1 (LRSAM1) gene cause CMT2P. We describe the genotype/phenotype analysis of a family...

Loss of the E3 ubiquitin ligase LRSAM1 sensitizes peripheral axons to degeneration in a mouse model of Charcot-Marie-Tooth disease

Charcot-Marie-Tooth disease (CMT) is a clinically and genetically heterogeneous condition characterized by peripheral axon degeneration with subsequent motor and sensory deficits. Several CMT gene products function in endosomal sorting and trafficking to the lysosome, suggesting that defects in this cellular pathway might present a common pathogenic mechanism for these conditions. LRSAM1 is an ...

Charcot–Marie–Tooth disease: Genetics, epidemiology and complications

Background and aims: Charcot Marie Tooth disease (CMT) is the most prevalent hereditary neuropathy and its frequency is 1 in 2500. CMT is a heterogeneous disease and has different clinical symptoms. The prevalence of CMT and involved genes differ in different countries. CMT patients experience considerable sleep problems and a higher risk of decreased quality of life. In this w...

A novel mutation in LRSAM1 causes axonal Charcot-Marie-Tooth disease with dominant inheritance

BACKGROUND Charcot-Marie-Tooth disease (CMT) refers to a heterogeneous group of genetic motor and sensory neuropathies. According to the primary site of damage, a distinction is made between demyelinating and axonal forms (CMT1 and 2, respectively, when inherited as an autosomal dominant trait). Leucine-rich repeat and sterile alpha motif-containing protein 1 (LRSAM1) is a ubiquitin-protein lig...
