TaySachs
TaySachs is a disease in which babies are born without one of the most important enzymes,
Hexosaminidase A (Hex A.) Healthy babies develop vision, movement, hearing, and other vital
functions in part because enzymes clear out fatty protein and other unwanted material that can
interfere with growth. Now these babies born without the Hex A enzyme affect the baby because
the fatty proteins just keep building up in the brain and affect the baby’s sight, hearing,
movement, and mental development.
Affects
Infancy onset
One of the dangers with Infants with Tay-Sachs disease Is that infants appear to develop
normally for the first few months of their lives. Then, as the babies nerve cells become covered
with fatty material, a relentless deterioration of physical and mental abilities sets in. As the
disease worsens the child’s vision deteriorates until complete blindness occurs, deaf, and unable
to swallow. Muscles begin to stiffen and paralysis sets in. However,TaySachs can be identified
by a simple blood test that measure beta-hexosamindase A activity. In order to for this to occur
both parents must carry the mutated gene in order to have an affected child. In these instances,
there is a 25 percent chance with each pregnancy that the child will be affected with TaySachs
disease. Prenatal diagnosis is available if desired.
Adult onset
From 20 to early thirties a much rarer form of the disorder occurs and is characteriazed by an
unsteady gait and progressive neurological deterioration. Another indication , persons with
TaySachs have “cherry-red” spots in their eyes.
Treatment
Presently there is no treatment for TaySachs disease. However anticonvulsant medicine may
intitially control seizures. Other supportive treatment includes proper nutrition and hydration and
other techniques to keep their airway open. Children may eventually need a feeding tube.
