TOMM70A
TOMMA70A Gene: Unraveling the Enigma
Description:
The TOMM70A gene, located on chromosome 22, encodes a protein known as Translocase of Outer Mitochondrial Membrane 70A (TOMM70A). TOMM70A is a crucial component of the TOM complex, a protein channel responsible for importing nuclear-encoded proteins into the mitochondria. It plays a vital role in maintaining mitochondrial protein homeostasis and ensuring cellular energy production.
Associated Diseases:
Mutations in the TOMM70A gene have been linked to several rare genetic diseases, including:
- Mitochondrial Myopathy, Cardiomyopathy, and Lactic Acidosis (MCCL): This condition manifests as muscle weakness, heart problems, and high levels of lactic acid in the blood.
- Optic Atrophy Plus Syndrome (OAP): Characterized by progressive loss of vision and additional neurological symptoms.
- Mitochondrial Encephalopathy with Lactic Acidosis and Stroke-like Episodes (MELAS): A complex disorder affecting the nervous system, muscles, and other organs.
Did you Know ?
Approximately 80% of MCCL cases are caused by mutations in the TOMM70A gene. This highlights the significant role of TOMM70A in this rare mitochondrial disease.
