Sample Question 1
Patient with B thalassemia major has what type of mutation?

*Non-sense>Premature termination of protein synthesis>No Bglobin chain thus HemA(a2B2) is decreased>Increase in Hem A2(a2D2) and HemF(A2Y2)

Frameshift mutation > Insertion or deletion of nucleotides leading to altered reading frame > Abnormal HemA(a2B2) production

Missense mutation > Alteration in amino acid sequence of Bglobin chain > HemA(a2B2) is abnormal

Silent mutation > No change in amino acid sequence of Bglobin chain > Normal HemA(a2B2) production

Sample Question 2
Patient with Sickle cell trait has what type of missense mutation?

Nonsense mutation

Frameshift mutation

*Don't get all wet if you see Glutamic acid substitution by Valine as this is RESULT of Missense(Point mutation that changes amino acid) mutation which involves Adenine Substitution by Thymidine.

Silent mutation

Sample Question 3
Between CAG(Ch4) and CGG(Xchr), which one is amplified in spermatogenesis and which one is amplified in Oogenesis?

CAG and CGG both are amplified during Spermatogenesis

CAG is amplified during Oogenesis and CGG is amplified during Spermatogenesis

*CGG is amplificated during Oogenesis(X-linked dominant disorder called Fragile X syndrome-Macroorchidism+Mental retardation)*CAG amplification happens during Spermatogenesis(Huntigton's disease -Autosomal Dominant disease>Caudate nucleus atrophy on MRI)*Number of triplet repeats is of prognostic value and increase in triplet numbers>Worse prognosis(Anticipation-increase in number of triplets>earlier onset of more severe symptoms with each generation)

CAG is amplified during both Spermatogenesis and Oogenesis

CGG is amplified during both Spermatogenesis and Oogenesis
