If you have a cherry red spot in your retina could you just be a carrier of Tay Sachs Disease?

Laboratory tests are required to determine if you are a carrier of Tay Sachs Disease. A cherry red spot in your retina is a symptom of the disease itself.

What genetic disorder is characterized by retina defects?
Tay-Sachs disease has an eye spot that is red on the back of the retina.
What are the phenotype effect of tay - sachs disease?
red spot on the retina of the eye
Who discovered the tay sachs disease?
''Tay-Sachs'' was named after Warren Tay, an ophthalmologist who discovered the occurring red spot in the retina in 1881, and Bernard Sachs, who described the cellular changes related to this disease in 1887.
Is Tay-Sachs disease due to heredity?
Tay- Sachs disease is inherited through offspring. If one of the parents are a carrier the one of the children might get it.
How is Tay Sachs Disease inherited?
A mutation of the HEX A gene of chromosome 15 causes Tay-Sachs disease. As a result, the protein hexosaminidase A is not formed properly and GM2 ganglioside, the lipid normally broken down by hexosaminidase A, accumulates to toxic levels (especially in the brain).
When was Sachs' Disease created?
Sachs' Disease was created in 1999.
What is genotype Tay Sachs disease?
a rare fatal hereditary disease, occurring chiefly in infants and children, esp. of eastern European Jewish origin, characterized by a red spot on the retina, gradual blindness, and paralysis.
Tay-Sachs disease is a human?
Tay-Sachs disease is a human genetic disorder.
What effect does Tay Sachs disease have on the body?
what effect does Tay-sachs disease have on the body?
If a husband is a carrier of Tay-Sachs and his wife is homozygous normal what are the chances of the children having tay-sachs?
This depends on the type of condition that Tay-Sachs is.Seeing that Tay-Sachs can be "carried" and not expressed, it is possible that it is a recessive condition. As such, the husband must be heterozygous, with an allele for Tay-Sachs, and a normal one.Since his wife is homozygous normal, and taking into account the fact that one allele is taken from each parent, it is not possible for the children to have Tay-Sachs. However, the children may be carriers.Note: This answer assumes that the gene for Tay-Sachs works in isolation.Edit: this is a valid answer, it may have been misunderstood by the questioner. Since the disease is recessive, a 'carrier' like the husband would be heterozygous (carrying one allele for Tay Sachs disease and the other allele is 'normal'). If you could be sure that the wife is definitely homozygous 'normal' (ie both alleles are 'normal'), and that the gene works in isolation, then the first answerer is right, there is no chance that a child would have Tay Sachs disease but there would be a 50% chance that the child would be a carrier . However, unless the wife has been definitively genotyped for this disease, there is always the chance that she is a carrier also which could result in children with Tay Sachs disease.It is 50% for the children to get the Tay-Sachs from the father, because the mother doesn't have any disease, do it is half.This answer is satifactory to anyone who knows anything about biology. The simple answer is none of the children will have it but there is a 50% chance of them being carriers. As stated above.
If someone is a heterozygous carrier of the tay-sachs gene what is their genotype?
if someone is a Heterozygous carrier of Tay-Sachs they would have to be Tt. Because TT is Homozygous.
What system or part of the body does tay sachs disease affect?
what effect does Tay-sachs disease have on the body?
