Is AADC Deficiency an Inherited Condition?

yes it is...

The gene for AADC deficiency maps to 7p12.1-p12.3 and is composed of 15 exons spanning 85 kilobases. Every gene consists of two alleles. One that comes from the father and one that comes from the mother. AADC deficiency is an inherited autosomal recessive trait – this means that each parent has a bad AADC allele that they pass on to their affected child.

Example 1:-

A child born to the parents below will not be affected by disease, as the parents are not carriers of a defective gene.




Example 2:-

A child born to the parents below has a 25% chance of inheriting AADC Deficiency, a 50% chance of becoming a carrier and a 25% chance of being free from any defective allele. Like the parents, a child who becomes a carrier is not usually expected to show any symptoms.
