40 Facts About Leukocyte Adhesion Deficiency

Source: Facts.net

Leukocyte Adhesion Deficiency (LAD) is a rare genetic disorder affecting the immune system. But what exactly is LAD? In simple terms, it's a condition where white blood cells, or leukocytes, can't properly move to infection sites. This makes it hard for the body to fight off infections. Why does this happen? The problem lies in the genes responsible for producing proteins that help leukocytes stick to blood vessel walls. Without these proteins, leukocytes can't exit the bloodstream to reach infected tissues. How common is it? LAD is extremely rare, with only a few hundred cases reported worldwide. What are the symptoms? Frequent infections, delayed wound healing, and severe gum disease are common signs. Can it be treated? Yes, treatments include antibiotics, bone marrow transplants, and gene therapy. Understanding LAD is crucial for managing this challenging condition.

Key Takeaways:

Leukocyte Adhesion Deficiency (LAD) is a rare genetic disorder that weakens the body's ability to fight infections, leading to recurrent infections, slow wound healing, and periodontitis.
Early diagnosis and proper treatment can significantly improve the prognosis and life expectancy of individuals with LAD, offering hope for a better quality of life through ongoing research and support networks.

What is Leukocyte Adhesion Deficiency?

Leukocyte Adhesion Deficiency (LAD) is a rare genetic disorder affecting the immune system. It impairs the body's ability to fight infections. Here are some intriguing facts about this condition.

Genetic Origin: LAD is caused by mutations in genes responsible for producing proteins that help white blood cells (leukocytes) stick to blood vessel walls.
Types of LAD: There are three types of LAD: LAD-1, LAD-2, and LAD-3. Each type is caused by different genetic mutations.
LAD-1: The most common type, LAD-1, results from mutations in the ITGB2 gene, which encodes the CD18 protein.
LAD-2: LAD-2 is caused by mutations in the SLC35C1 gene, affecting the transport of fucose, a sugar molecule essential for cell adhesion.
LAD-3: LAD-3 involves mutations in the FERMT3 gene, which affects the function of integrins, proteins crucial for cell adhesion and signaling.
