[Hereditary motor and sensory Lom-neuropathy--first Hungarian case report].
Hereditary motor and sensory neuropathy-Lom is an autosomal recessive disorder of the peripheral nervous system, which occurs only in the european Roma population. The symptoms start in the first decade with slowly progressive gait disturbance, weakness and wasting of distal upper extremity muscles, joint deformities and hearing loss develop later in the second and third decades. This disorder is caused by a homozygous missense mutation of the NDRG1 gene, located in the 8q24 region. The Schwann cell dysfunction is most probably caused by altered lipid metabolism as a consequence of the NDRG1 mutation. Molecular genetic testing can be a first diagnostic step among roma individuals showing a Lom neuropathy phenotype, making evaluation of such patients and also genetic counselling faster and easier. Screening for hereditary neuromuscular disorders in this genetically isolated community may become an important public health issue in the near future.
