Diamond–Blackfan anemia (DBA) is a rare, dominant geneticdisorder characterized by bone marrow malfunction, birthdefects, and a predisposition to certain cancers. Infants withDBA usually develop anemia in the first year of life, have lower thannormal production of red blood cells in their bone marrow, and havea high risk of developing leukemia and bone cancer. At the molecularlevel, DBA is caused by mutations in any one of 10 genes thatencode ribosomal proteins. The first-line therapy for DBA is steroidtreatment, but more than half of affected children develop resistanceto the drugs and in these cases, treatment is halted. DBA canbe treated successfully with bone marrow or stem cell transplantsfrom donors with closely matching immune system markers. Transplantsfrom unrelated donors have significant levels of complicationsand mortality. A couple with a child affected with DBA undergoes in vitro fertilization (IVF) and genetic testing of the resulting embryos to ensure that the embryos…
Null mutations are valuable genetic resources becausethey allow a researcher to determine what happens to anorganism in the complete absence of a particular protein. However, it is often not a trivial matter to determinewhether a mutation represents the null state of the gene.a. Geneticists sometimes use the following test forthe nullness of an allele in a diploid organism: If theabnormal phenotype seen in a homozygote for theallele is identical to that seen in a heterozygote(where one chromosome carries the allele in question and the homologous chromosome is known tobe completely deleted for the gene) then the alleleis null. What is the underlying rationale for thistest? What limitations might there be in interpreting such a result?b. Can you think of other methods to determinewhether an allele represents the null state of a particular gene?
Analysis of X-Linked Dominant and Recessive Traits Suppose a couple, both phenotypically normal, have two children: one unaffected daughter and one son affected with a genetic disorder. The phenotype ratio is 1:1, making it difficult to determine whether the trait is autosomal or X-linked. With your knowledge of genetics, what are the genotypes of the parents and children in the autosomal case? In the X-linked case?
Analysis of Autosomal Recessive and Dominant Traits Huntington disease is a rare, fatal disease that usually develops in the fourth or fifth decade of life. It is caused by a single autosomal dominant allele. A phenotypically normal man in his twenties who has a 2-year-old son of his own learns that his father has developed Huntington disease. What is the probability that he himself will develop the disease? What is the chance that his young son will eventually develop the disease?
Analysis of Autosomal Recessive and Dominant Traits In the following pedigree, assume that the father of the proband is homozygous for a rare trait. What pattern of inheritance is consistent with this pedigree? In particular, explain the phenotype of the proband.
A DNA variant has been found linked to a rare autosomal dominant disease in humans and can thus beused as a marker to follow inheritance of the diseaseallele. In an informative family (in which one parentis heterozygous for both the disease allele and the DNA marker in a known chromosomal arrangementof alleles, and his or her mate does not have the samealleles of the DNA variant), the reliability of such amarker as a predictor of the disease in a fetus is related to the map distance between the DNA markerand the gene causing the disease.Imagine that a man affected with the disease(genotype Dd) is heterozygous for the V1and V2forms of the DNA variant, with form V1on the samechromosome as the D allele and form V2on the samechromosome as d. His wife is V3V3dd, where V3isanother allele of the DNA marker. Typing of the fetusby amniocentesis reveals that the fetus has the V2andV3variants of the DNA marker. How likely is it thatthe fetus has inherited the disease allele D if thedistance…

Give genotypes for as many individuals in thepedigree as possible. (Invent your own defined allelesymbols.)c. Consider the four unaffected children of parentsIII-4 and III-5. In all four-child progenies from parentsof these genotypes, what proportion is expected tocontain all unaffected children?(picture added)
A 30 - year - old woman was undergoing therapy for b-thalassemia,a recessive trait caused by absence of or reduced synthesis ofthe hemoglobin b chain, a subunit of the oxygen-carrying moleculein red blood cells. In this condition, red blood cells are rapidlydestroyed, freeing a large amount of iron, which is deposited in tissuesand organs. The blood transfusions the patient had received every twoor three weeks since the age of 7 to stave off anemia were furtheraggravating iron buildup. Her major organs were showing damage, andshe was in danger of death from cardiac disease. Her physician suggestedthat she consider undergoing a hematopoietic (bone marrow)stem cell transplant (HSCT). Since these stem cells give rise to redblood cells, such a transplant could potentially restore her health. Whilethis might seem like an easy decision, it is not. Advanced cases havea high risk (almost 30 percent) for transplantation-related death. At thispoint, the woman is faced with a difficult and…

Six months pregnant, an expectant mother had a routineultrasound that showed that the limbs of the fetus wereunusually short. Her physician suspected that the babymight have a genetic form of dwarfism called achondroplasia,an autosomal dominant trait occurring with a frequency of about1 in 27,000 births. The parents were directed to a genetic counselorto discuss this diagnosis. In the conference, they learnedthat achondroplasia is caused by a mutant allele. Sometimes itis passed from one generation to another, but in 80 percent ofall cases it is the result of a spontaneous mutation that arisesin a gamete of one of the parents. They also learned that mostchildren with achondroplasia have normal intelligence and a normallife span. What information would be most relevant to concluding whichof the two mutation origins, inherited or new, most likelypertains in this case? How does this conclusion impact on thiscouple’s decision to have more children?
