Is it seizures? Non-epileptic events in a child with Tay-sachs disease

Three Novel Mutations in Iranian Patients with Tay-Sachs Disease

Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in‌ an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing m...

Tay-Sachs disease: a centenary.

Tay-Sachs Disease

In 1881 British ophthalmologist Warren Tay made an unusual observation. He reported a cherry-red spot on the retina of a one-year-old patient, a patient who was also showing signs of progressive degeneration of the central nervous system [4] as manifested in the child?s physical and mental retardation [5]. This cherry-red spot is a characteristic that would eventually come to be associated with...

Late-onset Tay-Sachs disease.

We discuss the assessment and differential diagnoses of a young adult Hungarian man with a 1-year history of a progressive and symmetric amyotrophic lateral sclerosis-like syndrome, along with irregular action tremor and stimulus-sensitive myoclonus of the arms. MR scan of the brain showed isolated cerebellar atrophy and formal neuropsychometric testing identified significant subclinical defici...

Screening for Tay-sachs Disease

Carrier screening programs have historically been focused within a particular group---e.g., Tay-Sachs among Ashkenazic Jews and sickle cell anemia among African Americans. With cystic fibrosis (CF), the potential target population is larger and less defined, which may introduce both technical and organizational complexity not present in past carrier screening. This appendix describes past carri...
