Many different types of mutations can occur within the body. Tay-Sachs disease is a deadly disorder that is caused by a missing codon in the gene coding for production of the hex A enzyme in the body. Which type of mutation is responsible for causing Tay-Sachs disease?

Verified Answer :

Answer:

Deletion mutation is responsible for Tay-Sachs disease.

Explanation:

Deletion mutation may be defined as the loss  of a sequence of a nucleotide base or entire deletion of chromosome at the time of DNA replication.

Tay Sachs disease is an autosomal recessive disorder and damages the central nervous system of the body. The alpha sub-unit of Hex A gene codes for the enzyme hexosaaminidase  has been lost in the Tay Sachs disease.

Thus, the deletion mutation is responsible for the Tay Sachs disease.

The type of mutation responsible for causing Tay-Sachs disease is a DELETION.

  • The Tay-Sachs disease is genetically inherited as an autosomal recessive disease.

  • The Tay-Sachs disease is caused by a mutation in the hexosaminidase subunit alpha (HEXA) gene, which encodes a fundamental enzyme found in the brain and spinal cord (i.e., beta-hexosaminidase A enzyme).

  • This neurodegenerative disorder is caused by a deletion allele (FCD) at the HEXA gene locus.

  • A deletion is a mutation involving the loss of one or more nucleotide bases.

In conclusion, the type of mutation responsible for causing Tay-Sachs disease is a DELETION.
