Health Conditions Related to Genetic Changes
Genetic changes can lead to various health conditions and disorders. These changes can occur in specific genes, which are responsible for the production of proteins and enzymes in our body. Understanding these genetic changes is crucial for diagnosing and treating different diseases.
One such gene is DDC, which encodes for the enzyme aromatic L-amino acid decarboxylase (AADC). Deficiency in this enzyme is associated with a rare genetic disorder called AADC deficiency. This condition affects the production of dopamine and serotonin, two important neurotransmitters in the brain.
Research studies have identified various genetic variants in the DDC gene that can lead to AADC deficiency. These variants result in reduced enzyme activity, leading to the characteristic symptoms of the disorder.
One of the most important and most popular changes to the health insurance landscape brought about by the passing of the Affordable Care Act was the prohibition against denying patients health insurance, or charging them more, if they had preexisting conditions. Research shows that 27% of Americans in the 18 to 64 age group have what would have been considered a “declinable medical condition” before the Affordable Care Act took effect, and in some regions, the percentage of patients with preexisting conditions rises to nearly four in 10, the Henry J. Kaiser Family Foundation
