Describe how mutations cause the following diseases and specifically what the mutation is:
1) Sickle cell anemia

2) G6PD deficiency

3) Thalassemia

4) Chondrodysplasia

5) Ehlers-Danlos Syndrome

Expert Solution

1)- sickle cell anemia - it causes the Hb present in rbc to distort to a sickle shape when deoxygenated. the type of mutation is point mutation in which there is change of only nucleotide in the gene for haemoglobin.

2)- G6PD deficiency- the type of mutation is substitution of single nucleotide means it is a point mutation. In this disease due to mutation the cell membrane of RBC become unstable and gets broken down due to absence of enzyme G6PD.

3)-thalassemia - it caused due to mutation in DNA of cells that make haemoglobin making the RBC useless as the oxygen cannot be transported by cells properly . The type of mutation is deletion of genetic material .

4)- condrodysplasia - it is a skeleton disorder characterised by formation of exostoses at the epiphysis and resulting in arrested development and deformity. It is a X linked dominant disease . Occurs due to mutation in PEX7 gene.

5)- ehlers danlos syndrome - this is an inherited disorder and it causes the weakning of connective tissue of our body . It mostly affect skin , joints and blood vessels . It this syndrome there is mutation in 19 genes .

1, Describe the mutation in the DNA molecule that leads to sickle cell disease. (What change is there in the DNA?) 2. How did this mutation affect the amino acid sequence in the hemoglobin protein? (Which amino acid was different?) 3. What was the effect on the actual hemoglobin protein caused by this amino acid change? 4. How do the changes in the red blood cells relate to the symptoms

What is the most common mutation found in the CFTR gene? c. Sickle cell anemia is also inherited as an autosomal recessive trait. What gene is mutated to cause sickle cell anemia? (1 pt) d. Why is it advantageous for a person to be heterozygous for the sickle cell trait? (2 pts)

Sickle cell anemia is a recessive disorder caused by a mutation in the hemoglobin A gene....

Sickle cell anemia is a recessive disorder caused by a mutation in the hemoglobin A gene. Persons with the disease have a variety of serious health issues related to fragile and sickling red blood cells including premature death, and infants sometimes die from complications. In regions of central Africa where malaria is endemic, the relative fitnesses for individuals that are homozygous for the wild type hemoglobin allele (HbA), heterozygous (HbAHbS), and homozygous for the sickle cell allele (HbS) are 0.8,...
