If a child has one parent with Marfan syndrome, what is the likelihood that the child will have Marfan syndrome?

10% chance

25% chance

50% chance

100% chance

Answer and Explanation

The Correct Answer is C

Marfan syndrome is a genetic disorder that affects the connective tissue, causing problems with the heart, blood vessels, eyes, bones, and joints. It is caused by a mutation in the FBN1 gene, which encodes for a protein called fibrillin-1. Marfan syndrome follows an autosomal dominant pattern of inheritance, which means that only one copy of the mutated gene is needed to cause the disorder. A person with Marfan syndrome has a 50% chance of passing on the mutated gene to each child, regardless of the gender of the parent or the child.

Correct Answer is C

Explanation

Benign prostatic hyperplasia (BPH) is a noncancerous enlargement of the prostate gland, a walnut-sized organ that surrounds the urethra in men. The enlarged prostate can compress the urethra and cause urinary problems, such as difficulty starting or stopping urination, weak urine stream, frequent or urgent urination, and blood in the urine. Transurethral prostate resection (TURP) is a surgical procedure that removes excess prostate tissue and relieves the pressure on the urethra.
