SEPN1
The SEP N1 Gene: An In-Depth Exploration
Description
The SEP N1 gene, also known as selenoprotein N1, encodes a protein that plays a vital role in various biological processes, including cellular redox homeostasis and immune function. This gene is located on the 1st chromosome and consists of 5 exons and 4 introns. The SEP N1 protein contains a conserved selenocysteine residue, which is essential for its antioxidant and anti-inflammatory properties.
Associated Diseases
Mutations in the SEP N1 gene have been linked to several diseases, including:
- Keshan disease: A potentially fatal cardiomyopathy characterized by heart failure and arrhythmias. It is primarily associated with selenium deficiency and mutations in the SEP N1 gene.
- Dilated cardiomyopathy: A progressive weakening and enlargement of the heart muscle that can lead to heart failure. Mutations in SEP N1 have been found in some cases of dilated cardiomyopathy.
- Myxedema: A condition characterized by swelling and thickening of the skin due to an underactive thyroid gland. Mutations in SEP N1 have been identified as a rare cause of myxedema.
Did you Know ?
Studies have shown that approximately 5% of individuals with Keshan disease have mutations in the SEP N1 gene. This underscores the significant role of this gene in the development of this devastating condition.
