An is a genetic condition that occurs when an individual inherits two copies of a mutated gene—one from each parent . This inheritance pattern typically occurs on the non-sex (numbered) chromosomes. In this scenario, both parents are usually "carriers" who do not show symptoms themselves but have a 25% chance of passing the disorder to their offspring with each pregnancy. Core Mechanism of Autosomal Recessive Inheritance
: For two carrier parents, the statistical breakdown for each child is: 25% risk of being affected (inheriting two mutated genes). 50% chance of being an asymptomatic carrier. autosomal recessive defect
