- Pathophysiology
- Autosomal recessive spinocerebellar ataxia 12 (ARSCA12) is a condition caused by mutations in the SCYL1 gene. The pathophysiology involves dysfunction in the SCYL1 protein, which plays a crucial role in the proper functioning of neurons. This protein is essential for normal cellular processes, including protein transport and regulation within cells. Disruptions in SCYL1 impair neuronal function and survival, particularly affecting the spinocerebellar pathways, leading to progressive ataxia, coordination problems, and other neurological deficits.
- Carrier Status
- Autosomal recessive spinocerebellar ataxia 12 (SCAR12) is an inherited neurological disorder. Carrier status refers to an individual who has one copy of the mutated gene responsible for the condition but does not typically show symptoms of the disorder. Carriers can pass the mutated gene to their offspring. In the context of SCAR12, if both parents are carriers, there is a 25% chance with each pregnancy that their child will inherit two copies of the mutated gene and thus be affected by the condition. "Nan" is not applicable or defined in this context.
- Mechanism
-
Autosomal recessive spinocerebellar ataxia 12 (SCAR12) is primarily caused by mutations in the ADCK3 gene, which encodes the protein aarF domain-containing kinase 3. The primary mechanism involves disrupted mitochondrial function due to impaired Coenzyme Q10 (CoQ10) biosynthesis.
Molecular mechanisms include:
1. Mutations in ADCK3 affect its kinase activity, essential for CoQ10 biosynthesis.
2. Reduced levels of CoQ10 lead to impaired mitochondrial electron transport chain function.
3. This results in less ATP production and increased oxidative stress, damaging neuronal cells, particularly in the cerebellum.
4. Damaged neurons in the cerebellum lead to the hallmark symptoms of ataxia, including impaired motor coordination and balance. - Treatment
