Background And Objectives: To clinically, genetically, and histopathologically characterize patients presenting with an unusual combination of distal myopathy and facial weakness, without involvement of upper limb or shoulder girdle muscles.
Methods: Two families with a novel form of actininopathy were identified. Patients had been followed up over 10 years.
Pathomechanisms of spinal and bulbar muscular atrophy (SBMA) have been extensively investigated and are partially understood, but no effective treatment is currently available for this disabling disorder. Its rarity, the slow disease progression, and lack of sensitive-to-change outcome measures render design and conduction of clinical trials a challenging task. Therefore, it is fundamental to strengthen the network of clinical centers interested in SBMA for clinical trial readiness.

Besides the obvious motor neuronopathy, additional findings in a substantial proportion of SBMA patients include sensory neuropathy and signs of androgen deficiency, such as poor sexual functioning and reduced fertility with gynaecomastia. The presence of elevated glucose, liver pathology or dyslipidaemia is less consistent features.
