Sickle-cell anaemia

Vedclass · Answer

(C) Sickle-cell anaemia is an autosome-linked recessive trait that can be transmitted from parents to the offspring when both the partners are carrier for the gene. The disease is controlled by a single pair of allele,$Hb^A$ and $Hb^S$. The defect is caused by the substitution of Glutamic acid (Glu) by Valine (Val) at the sixth position of the $\beta$-globin chain of the haemoglobin molecule. This substitution occurs due to the single base substitution at the sixth codon of the $\beta$-globin gene from $GAG$ to $GUG$.

In the $\beta$-globin chain of haemoglobin of an individual,if the sixth amino acid,Glutamic acid (Glu),is replaced by Valine (Val),then the individual will be suffering from:
