Chapter 12, Problem 12P
Many human genes are known to have homologs in the mouse genome. One approach to investigating human hereditary disease is to produce mutations of the mouse homologs of human genes by methods that can precisely target specific
a. Numerous studies of mutations of the mouse homologs of human genes have yielded valuable information about how gene mutations influence the human disease process. In general terms, describe how and why creating mutations of the mouse homologs can give information about human hereditary disease processes.
b. Despite the homologies that exist between human and mouse genes, some attempts to study human hereditary disease processes by inducing mutations in mouse genes indicate there is little to be learned about human disease in this way. In general terms, describe how and why the study of mouse gene mutations might fail to produce useful information about human disease processes.

Huntington disease (HD) can arise from a rare, short, in-frame addition of CAG nucleotide triplets within the huntingtin (HTT) gene coding region, which creates a disease-causing allele with the symptoms only appearing later in life. Using this information, describe an experiment that could be undertaken to determine whether a currently healthy young individual is a carrier of the HD-causing mutation. Describe the method you would use and how you would interpret the results of this experiment.

Different mutations in the WDR62 gene that inactivate gene function were found in the genomes of many different people with microcephaly. This information provided strong support for the idea that the WDR62 gene mutation causes microcephaly.
A.The human genome sequence identified WDR62 as one of the approximately 27, 000 genes in the human genome. What information about the function of WDR62 do you think was learned originally from the DNA sequence of the normal human genome?

- Leber Congenital Amaurosis (LCA) causes progressive vision loss due to defects in the gene that encodes RPE65 isomerase. Affected individuals are homozygous recessive for mutant alleles of the RPE65 gene. You are trying to determine the molecular nature of the mutations in three individuals with LCA. For ease of analysis, you may assume that each individual is homozygous for the same mutant allele (though the three individuals have different mutations than each other). You use the polymerase chain reaction to amplify DNA from each patient and you determine the sequence of the DNA and compare it to unaffected individuals. You identify the following differences. Note that the non-template strand of DNA is given and the changes are highlighted using red boldface. You can assume that the sequences are in the first reading frame (eg. the first three nucleotides of each sequence is a codon).

Why?arrow_forwardHuntington’s disease is a hereditary central nervous system disorder characterized by tandem repeats of the sequence 5'-CAG-3' in the gene that encodes a protein called huntingtin. The disease is progressive from generation to generation, meaning that in later generations the number of CAG repeats increases and the age of onset of symptoms decreases.
