What type of mutation is responsible for tay-sachs disease?

What type of mutation is responsible for tay-sachs disease?

Autosomal recessive: The medical term for this type of inheritance is autosomal recessive. Both parents must possess the recessive gene which is combined in the baby (receives two copies) and produces expression of the disorder. ...Read more

What type of genetic disorders are tay sachs disease and canavans examples of?

Genetic diseases: Tay sachs is an autosomal recessive genetic disease. It is a disease of the nervous system and is a member of the sphingolipidoses. Canavan disease is different autosomal recessive genetic disease of the nervous system and is a member of the leukodystrophies. Eastern european (ashkenazi) jews have a higher carrier rate for both of these diseases than the average population. Seek genetic counsiling. ...Read more

Any symptoms of tay-sachs disease?

Several forms exists: Infantile form: child appear normal until the age of 3-6 mo, when their development slows & muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. They also develop an exaggerated startle reaction to loud noises. As the disease progresses, seizures, vision&hearing loss, intellectual disabilities&paralysis may appear with abnormal eye exam. ...Read more

How does tay-sachs get transmitted?

How does tay-sachs get transmitted?

Genetics: Tay-sachs which almost always is presents in early infancy, is due to the inheritance of a defective gene one from each parent which is termed recessive inheritance. The parents do not show the disease although testing is possible askenazic jews and french canadians have an excess of this condition and will frequently get tested before pregnancy. It is fatal and severe. ...Read more

Tay-sachs disease is only injews, right?

Genetic disease: Tay-sachs is a horrible but rare genetic disease caused by an autosomal recessive mutation (abnormal gene) -- this means that both parents have to be carriers of the gene for a baby to inherit the disease. The tay-sachs gene is famous for being found in ashkenazic jews, but is also more common among french canadians and cajuns. Altho rare, anyone can carry the gene (approx 1/300 in north america). ...Read more

? Re-test?: The diagnosis of any life threatening illness in a patient that appears outwardly normal is going to bring initial shock & disbelief to most of us. Additional confirmatory tests by an alternate lab can be arranged for most conditions. Of note, carrier detection in the parents & other 1st degree family members would benefit your extended family.

What are the symptoms of tay-sachs disease?

Detrioration: An autosomal recessive genetic disorder. In its most common variant (known as infantile tay–sachs disease), it causes a progressive deterioration of mental and physical abilities that commences around six months of age. There is regression of development. Patients become deaf and blind and have a shortened life. It is quite sad. ...Read more

How long does someone with tay-sachs actually have to live?

Depends: Sxs of "classic" tay-sachs usually develop around 3-6 mos of age with muscle weakness. Between 6 -10 months of age, a child will not meet motor milestones & may lose the ability to perform tasks. After 8 -10 months of age, a baby will move less & become less responsive. At 2 yrs, they typically have trouble swallowing & become more unresponsive. Age of death-approx. 2-4 yrs often from pneumonia. ...Read more

Can you please tell me evolutionary implications of tay-sachs disease?

See below: The tay-sachs disease is a genetic malformation that can present in childhood or later years. The evolutionary implications are that the infantile form usually dies before it
can reproduce and so dies out. The adult variety can reproduce and pass the genetic malformation along to its offspring. The adult variety does not appear to be a successful mutation. ...Read more

Is it uncommon for tay sachs disease to start to manifest later in life?

Very Rare: Tay sachs is a metabolic defect that begins to cause problems immediately after birth. Neurologic abnormalities are identified during the first year of life and these children all die in the first years of life. There may be another neurologic disorder that has some of the clinical features of tay sachs that shows up later. ...Read more

, how come only jews get tay sachs?

, how come only jews get tay sachs?

Heredity: Jews were isolated in communities in eastern europe when they were forbidden to mix with the rest of the populace. At some time about 300-400 years ago, a mutation occurred which led to tay sachs in that community. Since outmixture was not common, the gene stayed in that population and since it was recessive, it could propogate. Jews of that origin can marry and the disease shows up. ...Read more
