X-linked Agammaglobulinemia (XLA)

X-linked Agammaglobulinemia (XLA) is a genetic condition where the body cannot produce antibodies, making it difficult to fight infections. It is caused by a mutation in the BTK gene, which is located on the X chromosome. This condition primarily affects males, as they have only one X chromosome. Individuals with XLA are more prone to recurrent infections, especially from bacteria. Treatment typically involves regular infusions of immunoglobulin (antibodies) to help bolster the immune system and prevent infections, allowing those affected to lead healthier lives. Early diagnosis and management are crucial for better outcomes.
