Question

Mutations in the lamin A gene are responsible for very diverse disorders because:

a) The gene has multiple functions
b) The gene is located on the X chromosome
c) The gene is not involved in any essential processes
d) The mutations are not hereditary

Answer 1

Mutations in the lamin A gene cause diverse disorders due to the gene's multiple critical functions in providing structural support and involvement in cellular processes. These mutations can be hereditary and lead to a range of diseases known as laminopathies.

Step-by-step explanation:

Mutations in the lamin A gene are linked to diverse disorders because the gene has multiple functions. The lamin A protein is critical for providing structural support to the cell nucleus and is involved in numerous cellular processes. Consequently, mutations that alter the function of this protein can lead to a range of diseases, known as laminopathies, which include muscular dystrophies, lipodystrophies, and premature aging syndromes. These disorders are not determined by sex chromosomes, as lamin A is not located on the X chromosome. In addition, these mutations can be hereditary, meaning they can be passed down from parents to offspring, and are involved in essential cellular processes, making them potentially serious and life-altering.
