Q. Which among the given is a Dominant Autosomal Disorder

Explanation by: Ruchi Sharma

In an autosomal dominant disorder, the mutated gene is a dominant gene situated on one of the nonsex chromosomes (autosomes). The early-onset form of Alzheimer disease is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person inherits the altered gene from one affected parent.
