ADORA3
Adora3: Unraveling the Mysteries of a Gene Linked to Autism
Description
ADORA3, located on chromosome 1q32.1, is a gene responsible for encoding the A3 adenosine receptor, a type of G protein-coupled receptor. This receptor plays a crucial role in regulating synaptic plasticity, the adaptability of neuronal connections, and neurotransmission in the brain.
Associated Diseases
Mutations in ADORA3 have been strongly linked to several neurodevelopmental disorders, including:
- Autism spectrum disorder (ASD): The most common association, with mutations in ADORA3 found in up to 2% of ASD cases.
- Intellectual disability: Often co-occurring with ASD.
- Attention deficit hyperactivity disorder (ADHD): Studies have suggested a possible association, but the evidence is less conclusive.
Did you Know ?
Approximately 50% of individuals with ASD who carry ADORA3 mutations also have macrocephaly, an abnormally large head circumference.
