TMEM133
The tmem133 Gene: Unraveling Its Role in Health and Disease
Description
The tmem133 gene, located on chromosome 19, encodes a transmembrane protein known as transmembrane protein 133 (TMEM133). This protein is primarily expressed in the brain, particularly in neurons and glial cells. TMEM133 plays a crucial role in regulating cellular processes, including ion transport, cell migration, and synaptic plasticity.
Associated Diseases
Mutations in the tmem133 gene have been linked to several neurological conditions, including:
- Spinocerebellar ataxia type 31 (SCA31): A progressive neurodegenerative disorder characterized by difficulties with coordination, balance, and speech.
- Episodic ataxia type 2 (EA2): A rare condition causing sudden, transient episodes of incoordination and slurred speech.
- DYT32 dystonia: A type of movement disorder involving abnormal muscle contractions.
- Intellectual disability: TMEM133 mutations have been associated with intellectual disability, particularly in children with SCA31.
Did you Know ?
Approximately 0.5% of individuals with neurodegenerative diseases, such as SCA31, carry mutations in the tmem133 gene. This highlights the potential significance of TMEM133 in neurological health.
