Pathophysiology: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is primarily caused by mutations in the NOTCH3 gene. This gene encodes a receptor involved in the development and function of vascular smooth muscle cells. Mutations lead to the accumulation of granular osmiophilic material in the blood vessel walls, particularly small and medium-sized arteries. These changes result in progressive damage to small blood vessels in the brain, leading to reduced blood flow, chronic ischemia, and subsequent tissue damage. The condition manifests as recurrent strokes, migraines, mood disturbances, and progressive cognitive decline.
Carrier Status: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a genetic disorder. Carrier status typically refers to conditions that are inherited in an autosomal recessive manner, where two mutations are needed to manifest the disease. CADASIL, however, is inherited in an autosomal dominant manner, meaning only one mutated copy of the responsible gene (NOTCH3) is needed to cause the disease. Therefore, an individual cannot be a "carrier" in the traditional sense; if they have the mutation, they are likely to express the disease phenotype. There’s no concept of a silent carrier as in recessive conditions.

If you refer to "nan," this could relate to a data entry placeholder and has no clinical significance in this context.
Mechanism: CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a genetic disorder affecting small blood vessels in the brain.

**Mechanism:**
1. CADASIL is caused by mutations in the **NOTCH3** gene, which encodes the NOTCH3 receptor, a protein expressed mainly in vascular smooth muscle cells.
2. Mutations typically involve **missense mutations** leading to the accumulation of the NOTCH3 extracellular domain (N3ECD) in the walls of small arteries.
3. This accumulation results in **degenerative changes** such as vascular smooth muscle cell loss and fibrosis of the vessel wall.
4. These changes impair blood flow and contribute to microvascular dysfunction, causing chronic ischemia and recurrent strokes.

**Molecular Mechanisms:**
1. The NOTCH3 mutations involve an increased number of **cysteine residues** in epidermal growth factor-like (EGFL) repeats of the NOTCH3 receptor.
2. This disrupts the normal folding and functioning of the NOTCH3 protein.
3. The defective NOTCH3 protein aggregates in the small arterial walls, primarily in the brain, leading to **vascular smooth muscle cell degeneration**.
4. These aggregates initiate a cascade of events including oxidative stress, inflammation, and further cellular damage.
5. The vascular changes lead to **chronic hypoperfusion** and white matter lesions, contributing to the clinical manifestations such as migraine, mood disturbances, cognitive decline, and recurrent ischemic strokes.
Treatment: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) currently has no cure, and treatment primarily focuses on symptom management and preventing complications. This may include controlling risk factors such as hypertension, managing migraines with appropriate medications, using antiplatelet agents like aspirin to reduce the risk of stroke, and addressing cognitive or mood symptoms through supportive therapies. Regular monitoring and multidisciplinary care are essential for managing this condition effectively.
