Tay Sachs Disease

Tay-Sachs disease (TSD) is a fatal genetic disorder, most commonly occurring in children, that results in progressive destruction of the nervous system. Tay-Sachs is caused by the absence of a vital enzyme called hexosaminidase-A (Hex-A).

What is Tay-Sachs Disease?

Tay-Sachs disease (abbreviated TSD, also known as GM2 gangliosidosis or Hexosaminidase A deficiency) is an autosomal recessive genetic disorder. In its most common variant known as infantile Tay-Sachs disease it presents with a relentless deterioration of mental and physical abilities which commences at 6 months of age and usually results in death by the age of four.

Study identifies a potential treatment for Sandhoff and Tay-Sachs diseases

In a groundbreaking study, researchers at McMaster University have identified a potential treatment for Sandhoff and Tay-Sachs diseases—two rare, often fatal lysosomal storage disorders that cause progressive damage to nerve cells in the brain and spinal cord.

Known genes account for most undiagnosed cases of developmental disorders

Scientists have conducted the largest and most diverse study to date on how recessive genetic changes contribute to developmental disorders. They found that most undiagnosed cases that are due to recessive causes are linked to genes we already know about, and suggest a shift in research focus could improve diagnosis rates.
