Learn About Activated PI3K Delta Syndrome (APDS)

What is the definition of Activated PI3K Delta Syndrome (APDS)?

Activated PI3K-delta syndrome (also known as APDS) is a disorder that impairs the immune system. Individuals with this condition often have low numbers of white blood cells (lymphopenia), particularly B cells and T cells. Normally, these cells recognize and attack foreign invaders, such as viruses and bacteria, to prevent infection. The severity of activated PI3K-delta syndrome varies widely. Some people may have multiple, severe infections while others show mild symptoms to none at all.

What are the causes of Activated PI3K Delta Syndrome (APDS)?

Activated PI3K-delta syndrome is caused by variants (also called mutations) in the PIK3CD gene and the PIK3R1 gene. Activated PI3K-delta syndrome type 1 is caused by variants in the PIK3CD gene, which provides instructions for making a protein called p110 delta (p110δ). Activated PI3K-delta syndrome type 2 is caused by variants in the PIK3R1 gene. This gene provides instructions for making slightly different versions of another protein; the most common version is called p85 alpha (p85α).

How prevalent is Activated PI3K Delta Syndrome (APDS)?

Activated PI3K-delta syndrome is considered a rare disorder, but its exact prevalence is unknown.

Is Activated PI3K Delta Syndrome (APDS) an inherited disorder?

Activated PI3K-delta syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
