Background and Objectives Charcot-Marie-Tooth disease (CMT) is a syndrome of a hereditary neurodegenerative condition affecting the peripheral nervous system and is a single gene disorder. Deep phenotyping coupled with advanced genetic techniques is critical in discovering new genetic defects of rare genetic disorders such as CMT. Methods We applied multidisciplinary investigations to examine…

Objective Systemic capillary leak syndrome (SCLS) is a rare condition associated with episodes of hypotension, hemoconcentration, hypoalbuminemia, and rhabdomyolysis. We describe a middle-aged man presenting with several distinct SCLS-like episodes, the last being fatal. In addition, in the year before the final event, he developed rapid cognitive decline with contrast-enhancing lesions on MRI…

Background and Objectives After clinical evaluation, the molecular diagnosis of type 1 facioscapulohumeral dystrophy (FSHD1) relies in most laboratories on the detection of a shortened D4Z4 array at the 4q35 locus by Southern blotting. In many instances, this molecular diagnosis remains inconclusive and requires additional experiments to determine the number of D4Z4 units or identify somatic…

Objective Autosomal recessive spinocerebellar ataxia type 9 (SCAR9) has received attention due to its potential response to coenzyme Q10 (CoQ10) supplementation; however, the response has so far been limited and variable. Methods We report a SCAR9 patient with severe hypophosphatemia who responded well to CoQ10 and phosphate repletion. Results A 70-year-old man (the offspring of a…
