Autosomal Dominant Thrombotic Microangiopathy (ADTM) is a rare genetic disorder that affects the small blood vessels in the body. This condition can lead to various health issues, including problems with blood cells and organs. In this guide, we’ll break down everything you need to know about ADTM in simple language, making it easy to understand.
Autosomal Dominant Thrombotic Microangiopathy (ADTM) is a genetic condition that affects the body’s small blood vessels (microangiopathy). The term “autosomal dominant” means that the disorder is inherited through a dominant gene located on one of the non-sex chromosomes (autosomes). If one parent has the defective gene, there’s a 50% chance their child will inherit the condition.
ADTM leads to the formation of small blood clots (thrombi) in the microvasculature, which can damage organs and reduce the number of healthy blood cells. This can cause various health problems, including anemia, kidney issues, and neurological symptoms.
Pathophysiology
Structure
In ADTM, the small blood vessels (arterioles and capillaries) become narrowed or blocked due to the formation of tiny clots. This restricts blood flow to organs and tissues, leading to damage. The affected structures include:
- Blood Vessels: Narrowed and clotted, reducing blood flow.
- Organs: Especially the kidneys, brain, and heart can be affected due to reduced blood supply.
Blood
ADTM affects blood cells in several ways:
- Red Blood Cells (RBCs): Clots can break RBCs apart, leading to hemolytic anemia.
- Platelets: Clot formation uses up platelets, causing low platelet counts (thrombocytopenia).
- White Blood Cells: May also be affected, though less commonly.
Nerve Supply
While ADTM primarily affects blood vessels and blood cells, reduced blood flow can indirectly impact the nervous system. Symptoms may include:
- Neurological Issues: Such as headaches, confusion, seizures, or weakness due to insufficient blood supply to the brain.
Types of ADTM
ADTM can be categorized based on genetic mutations and the specific pathways affected:
- Complement-Mediated ADTM: Involves mutations in genes regulating the complement system, a part of the immune system.
- Non-Complement-Mediated ADTM: Caused by mutations in other genes affecting blood vessel integrity and clot formation.
Causes
ADTM is caused by inherited genetic mutations. Here are 20 potential causes related to genetic factors:
- Mutations in the ADAMTS13 Gene: Leading to reduced activity of the enzyme that breaks down clotting proteins.
