FAM19A2
Title: Exploring FAM19A2: A Gene Linked to Neurodevelopmental Disorders
Section 1: Description
FAM19A2 is a gene located on the short arm of chromosome 15. It encodes a protein called family with sequence similarity 19 member A2, which plays a crucial role in maintaining the structure and function of synapses, the connections between neurons. Mutations in FAM19A2 have been implicated in a range of neurodevelopmental disorders, including autism spectrum disorder (ASD), intellectual disability, and epilepsy.
Section 2: Associated Diseases
Disorders associated with FAM19A2 mutations include:
- Autism Spectrum Disorder (ASD): FAM19A2 mutations have been identified in individuals with ASD characterized by social difficulties, communication deficits, and repetitive behaviors.
- Intellectual Disability: Mutations in FAM19A2 have been linked to various degrees of intellectual disability, ranging from mild to severe impairment.
- Epilepsy: Some individuals with FAM19A2 mutations experience seizures, ranging from mild and infrequent to severe and intractable.
Did you Know ?
Approximately 1% of individuals with ASD have mutations in FAM19A2. This highlights the significant impact of this gene on neurodevelopment.
