HH PART I Hereditаry hemоchrоmаtоsis (HH) is аn autosomal recessive disorder that results in an over-absorption of iron, which cannot be excreted from the body resulting in iron overload. This usually results in damage to a number of internal organs (including the liver and heart), and ultimately death if left untreated. HH is the most common autosomal recessive disease in European populations. Early diagnosis is important, because the toxic effects of iron overload can be wholly prevented by a combination of treatments including bloodletting, diet modification, and the administration of certain drugs (iron chelators). Detection of hemochromatosis can be done through routine blood tests, MRIs, and liver biopsy. The hereditary form of the disease is most commonly due (90% of cases) to a mutation in the HFE gene, with homozygosity for the C282Y allele being the genotype responsible for nearly all clinical findings of hemochromatosis; however penetrance and expressivity of the disease varies, and not all homozygotes show the disorder, or have symptoms with the same severity. A genetic test has been developed to detect the C282Y allele. It is an allele-specific assay, which can detect the variant nucleotide responsible for the missense mutation at amino acid 282. Sensitivity for the homozygote genotype is 98.4% (false negative rate of 1.6%), and specificity for non-homozygous genotypes is 99.8% (false positive rate of 0.2%). A genetic test is typically recommended for people who are relatives of affected individuals, or to confirm a diagnosis based on other clinical findings. 1) The genetic test for the C282Y allele will confirm 90% of hereditary hemochromatosis genotypes. What about the other 10%? Do you think this is an acceptable test to use if it will miss 10% of genotypes that may lead to disease? Why or why not?
Cоnsider twо lоci, A аnd B, eаch with two аlleles: A and a, & B and b. You sample these loci in 500 individuals within two different populations and find the following haplotype (NOT genotype) frequencies: In which population are the alleles in linkage equilibrium?

There must be some kind of treatment or therapy that will address disease symptoms. Do you think that hereditary hemochromatosis is a good candidate for genetic testing? Explain your answer.
