Is marfan syndrome a sex-linked disease?

No: Marfan syndrome is an autosomal dominant connective tissue disorder caused by abnormal microfibrillin protein. If a parent is affected by the disorder, their offspring has a 50/50 chance of inheriting it, regardless of whether the baby is a boy or a girl.

No: Marfan syndrome is autosomal dominant, not sex-linked. About one in 3000-5000 people have Marfan syndrome. It affects an equal number of males and females.
