A child exhibiting early symptoms of progeria undergoes genetic testing.A gene coding for which protein is likely to be mutated?

Question

Quizplus · Accepted Answer

Progeria is a rare genetic disorder characterized by premature aging in children. It is caused by a mutation in the LMNA gene, which codes for lamin-A protein. Lamin-A is a component of the nuclear envelope and is responsible for maintaining the structural integrity of the nucleus. A mutation in this gene results in abnormal lamin-A protein production, which causes the characteristic symptoms of progeria.
