Huntington's disease is caused by a dominant allele
One of the leading causes of blindness in the US, glaucoma results from a group of eye conditions which causes optic nerve damage due to abnormally high pressure inside the eye.
The DNA sequence of the allele that causes Tay-Sachs disease is different from that of the normal allele. This difference in the DNA sequence allows for specific genetic tests to be conducted to identify the presence of the Tay-Sachs disease allele in individuals.
An individual with a recessive disease-causing allele on one chromosome and a normal allele on the other chromosome is referred to as a heterozygote for that gene. Since the disease is recessive, the normal allele typically masks the effects of the recessive allele, meaning the individual usually does not exhibit symptoms of the disease. However, they can still pass the recessive allele to their offspring.
Yes, Huntington's disease is autosomal dominant with high penetrance. Every individual who inherits the allele gets the disease.
They are a carrier of the disease but do not show any symptoms because they have one normal allele that can compensate for the recessive disease-causing allele. If they have children with a partner who is also a carrier, there is a chance their offspring may inherit two copies of the disease-causing allele and develop the disease.
Yes, glaucoma is a serious eye disease. This eye problem can lead to permanent vision loss and this disease doesn't have any major symptoms. So, early detection of this eye problem becomes hard.
