Stimulus-Induced Drop Episodes in Coffin-Lowry Syndrome

Stimulus-induced drop episodes in Coffin-Lowry syndrome.

OBJECTIVE Coffin-Lowry syndrome (CLS) is a rare disorder characterized by moderate to severe mental retardation, facial dysmorphism, tapering digits, and skeletal deformity. Paroxysmal drop attacks occur in patients with CLS, characterized by sudden loss of muscle tone induced by unexpected tactile or auditory stimuli. Our objective is to characterize these attacks better using neurophysiologic...

Coffin-Lowry Syndrome

Disease characteristics. Coffin-Lowry syndrome (CLS) is characterized by severe to profound mental retardation in males. Intellect ranges from normal to profoundly retarded in heterozygous females. The facial appearance is characteristic in the affected, older male child or adult. The hands are short, soft, and fleshy, often with remarkably hyperextensible fingers that taper from wide (proximal...

Stimulus-induced myoclonus treated effectively with clonazepam in genetically confirmed Coffin–Lowry syndrome☆

PURPOSE Coffin-Lowry syndrome (CLS) is a rare X-linked semidominant syndromic genetic disorder that is characterized by typical facial and radiologic findings, psychomotor and growth retardation, and various skeletal anomalies. A distinctive paroxysmal disorder called stimulus-bound myoclonus is clinically heterogeneous and is generally characterized by a sudden loss of muscle tone that is rega...
