CHCHD10

CHCHD10 is a gene that encodes the mitochondrial protein CHCHD10. This protein is involved in the regulation of mitochondrial dynamics, including fusion and fission, and is essential for maintaining mitochondrial integrity. Mutations in the CHCHD10 gene have been associated with several neurodegenerative diseases, including frontotemporal dementia, amyotrophic lateral sclerosis, and spinal muscular atrophy.

Location of the CHCHD10 gene on human chromosome 22.

Structure

The CHCHD10 gene is located on the short (p) arm of chromosome 22 at position 13.33. The gene spans approximately 15 kilobases and consists of four exons. The encoded protein is 142 amino acids in length and contains a coiled-coil domain and a CHCH domain.

Function

The CHCHD10 protein is localized in the mitochondrial intermembrane space and is involved in the regulation of mitochondrial dynamics. It plays a crucial role in maintaining mitochondrial integrity by participating in the process of mitochondrial fusion and fission. The protein also has a role in the regulation of mitochondrial cristae morphology and in the maintenance of mitochondrial DNA.

Clinical significance

Mutations in the CHCHD10 gene have been associated with several neurodegenerative diseases. These include frontotemporal dementia, amyotrophic lateral sclerosis, and spinal muscular atrophy. The mutations lead to the production of a faulty CHCHD10 protein that cannot properly regulate mitochondrial dynamics, leading to mitochondrial dysfunction and, ultimately, neuronal death.

Research

Research into the CHCHD10 gene and its associated diseases is ongoing. Current research focuses on understanding the exact mechanisms by which mutations in the CHCHD10 gene lead to neurodegenerative diseases and on developing potential therapeutic strategies.
