TL;DR: The association between genotype and degree of hearing loss in persons with HI and biallelic GJB2 mutations was assessed and two genotypes had significantly more-severe HI than that of 35delG homozygotes.

TL;DR: The same mutation (K141N) in small heat-shock 22-kDa protein 8 (encoded by HSPB8) is identified in two pedigrees with distal hereditary motor neuropathy type II linked to chromosome 12q24.3, providing further evidence that mutations in heat- shock proteins have an important role in neurodegenerative disorders.

TL;DR: Electrophysiological data showed in the majority of patients normal to slightly reduced nerve conduction velocities with often severely reduced amplitudes of the compound motor and sensory nerve action potentials, whereas a smaller group experienced a later onset and milder disease course.

TL;DR: These findings represent the first example of an RNA exosome core component gene that is responsible for a human disease and further implicate dysregulation of RNA processing in cerebellar and spinal motor neuron maldevelopment and degeneration.

TL;DR: It is shown that HSAN-I is consistently associated with an increased formation of the neurotoxic 1-deoxysphinganine, suggesting a common pathomechanism for HSAN, which is also associated with the group of HSAN neuropathies associated with SPT defects.
