describe three autosomal dominant conditions in humans

Expert Solution

Autosomal dominant disorders are those in which only one mutated copy of the gene is responsible for the person to be affected by it. Examples of autsomal dominant disorders are Huntington's disease, Marfan's syndrome and neurofibromatosis.

Huntington's disease is a rare hereditary neurological disease that is characterized by irregular and involuntary movement of the muscles and progressive loss of cognitive ability.

Marfan's syndrome is a rare hereditary connective tissue disorder that affects the skeleton, heart and eyes. It involves mutation to a gene that makes fibrillin, that results in the production of abnormal connective tissue.

Neurofibromatosis can be characterized into Type 1 and Type 2 disorders. Neurofibromatosis Type 1 is more common of the two disorders and is characterized by pale brown spots on the skin and benign soft tumors arising from abnormal growth of nerves.

Nuerofibromatosis Type 2 is much rarer and is chracterized by tumors of the auditory canal in the ear and by small number of soft brown spots.

In humans, hypercholesterolemia is a dominant autosomal disorder. Color-blindness is a recessive disorder carried on the X-chromosome. A woman with normal vision who does not have hypercholesterolemia takes her daughter to a doctor for an examination. In the course of the examination, the doctor discovers that the girl is color-blind and has hypercholesterolemia. What does the doctor automatically know about the genotype and phenotype of the girl’s father?

Retinitis pigmentosa, a form of blindness in humans, may be caused by a dominant autosomal gene,...

Retinitis pigmentosa, a form of blindness in humans, may be caused by a dominant autosomal gene, R, or a recessive autosomal gene, a. Thus only A_ rr individuals have normal sight. An afflicted man whose parents are both normal marries a woman of genotype AaRr. (A) What is the genotype of the afflicted man? (B) What proportion of the children are expected to suffer from this affliction if R and A map to different chromosomes?

Genetic Inheritance Patterns: Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked

Genetic Inheritance Patterns: Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked. Apparently the dominant forms are often less severe. Usher’s Syndrome is an autosomal recessive inheritance (i.e., you must get a copy of the defective gene from your Mom and one from your Dad). Autosomal means it is not carried on one of the chromosomes that determines sex. One website (http://www.emedicine.com/oph/topic704.htm) says that Usher’s Syndrome Type II has been mapped to chromosome arm 1qe. Usher’s Type II...

If there is an affected heterozygous parent with Huntington’s disease (an autosomal dominant disease) who has children with an unaffected parent, what are the chances of them having kids with Huntington’s disease? If there are two parents who are heterozygous carriers for Cystic Fibrosis disease (an autosomal recessive disease) What are the chances of them having a child with Cystic Fibrosis disease? What are the chances of them having a child who is a carrier for Cystic Fibrosis? What are...

In a population of anteaters in South Africa, T1 and T2 are autosomal, incompletely dominant alleles that control tongue length. The alleles are polymorphic in this population, with f(T1) = 0.95 and f(T2) = 0.05. Anteaters that have long tongues are T1T1, T1T2 individuals have medium-length tongues, and T2T2 individuals have short tongues. A disease that wipes out the ants with deep nests occurs in this ecosystem, exerting strong natural selection on the long-tongued anteaters (they are ineffective at eating...

A man is heterozygous for achondroplasia for which the autosomal dominant A allele confers extremely short stature. His wife's genotype is aa and she is normal height. They have five children together. What is the probability that any two of their five children will have the short stature phenotype, in any birth order?
