Tay–Sachs diseaseThe article presents a case study of a 2-year-old girl who had mild developmental delay and was born at 36 weeks 6 days, after an uncomplicated pregnancy, weighing 2,706 g. It discusses this case of early juvenile Tay–Sachs disease (TSD) with atypical symptoms including...
Tay-Sachs diseaseis the prototype of adegenerative diseaseof gray matter in infancy (seeTable 29.2). Onset in the first few weeks of life, although uncommon, may occur. (More commonly, onset is at approximately 3 months.) The principal initialclinical featuresare irritability and hypersensitivity ...
Symptoms 症状 1.婴儿型:最常见,最严重 3-6 个月开始有症状体征,生存期很短,通常只有几年 症状体征:①易激惹,在受到较大声音刺激时会有夸张的惊跳反应;②眼睛的“樱桃红”斑点;③无法运动,包括翻身、爬行、坐起;④肌肉无力,进行性瘫痪;⑤运动问题;⑥癫痫发作;⑦视力丧失,致盲;⑧听力丧失,致聋;⑨吞咽问题;...
One of the symptoms of this disease was first described in 1883 by British ophthalmologistWarren Tay, who saw a cherry-red spot on the back of the eye of affected infants. In 1887, American neurologistBernard Sachsdescribed the profound neurological symptoms of Tay-Sachs in a seminal paper: "...

infantile-onset phenotype is a fatal neurodegenerative disease of infancy, while the late-onset form, designated LOTS (for late-onset Tay–Sachs), is characterized by onset in childhood, adolescence, or adult life characterized by muscle weakness, ataxia and dysarthria, and other neurologic symptoms...

Tay-Sachs disease (TSD) is a neurodegenerative disease that is caused by mutations in the HEXA gene. These mutation cause low or absent activity of the enzyme beta-hexosaminidase A which leads to GM2 build up in brain and spinal cells causing muscle weakness, regression of milestones, and dif...
No, Tay-Sachs disease typically presents in infancy or early childhood. It is a rare genetic disorder that results in the destruction of nerve cells in the brain and spinal cord. Adults who carry the gene mutation for Tay-Sachs disease do not develop symptoms of the disease themselves, but ...
