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?
substitution
replacement
insertion
deletion

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

Answer : The correct answer is -

deletion.

TSD (Tay Sachs disease) is primarily an inherited (autosomal recessive) neurodegenerative disease that is caused due to the deficiency of an enzyme, HEXA (hexosaminidase A).

A deletion mutation in the gene HEXA (that provides genetic instruction for the alpha subunit of the enzyme) results in this disease. This enzyme is associated to play a significant role in the central nervous system (brain and spinal cord).

Symptoms associated with this disease include seizures, loss of motor skills, blindness, weakening of muscles etc.
