Short answer · Medically reviewed summary · Last updated: 2026-05-08
Chronic Granulomatous Disease (CGD) is a rare primary immunodeficiency with an estimated global prevalence of approximately 1 in 200,000 to 250,000 individuals. While incidence rates vary by region, it is estimated that 1 in 200,000 live births are affected, though these figures likely underestimate the true burden due to historic underdiagnosis. Is Chronic Granulomatous Disease considered rare? Yes, Chronic Granulomatous Disease is classified as a rare disease.
1 people with Chronic Granulomatous Disease have shared their first-person experience on this question at DiseaseMaps.
What is the prevalence of Chronic Granulomatous Disease?
Prevalence of Chronic Granulomatous Disease: how many people are affected worldwide, differences by sex and region, with sources.
Chronic Granulomatous Disease (CGD) is a rare primary immunodeficiency with an estimated global prevalence of approximately 1 in 200,000 to 250,000 individuals. While incidence rates vary by region, it is estimated that 1 in 200,000 live births are affected, though these figures likely underestimate the true burden due to historic underdiagnosis.
Is Chronic Granulomatous Disease considered rare?
Yes, Chronic Granulomatous Disease is classified as a rare disease. Because it is a complex genetic disorder affecting the immune system's ability to destroy certain bacteria and fungi, many cases go unrecognized until a severe infection occurs. Within the DiseaseMaps.org community, 60 people with Chronic Granulomatous Disease have connected to share their experiences, providing a crucial, real-world perspective on living with this condition that often exceeds the data found in clinical textbooks.
How does the prevalence of Chronic Granulomatous Disease vary by gender and age?
The inheritance pattern of Chronic Granulomatous Disease significantly influences its distribution:
- Gender: Approximately 65-70% of cases are X-linked recessive, meaning the disease predominantly affects males. Autosomal recessive forms, which affect males and females equally, account for the remaining 30-35%.
- Age of Onset: While Chronic Granulomatous Disease is typically diagnosed in childhood—often before the age of 5—milder genetic variants can sometimes remain undiagnosed until adolescence or early adulthood.
Why are statistics for Chronic Granulomatous Disease difficult to track?
Accurate epidemiological data for Chronic Granulomatous Disease is challenging to maintain for several reasons:
- Underdiagnosis: Patients with partial enzyme function may experience fewer severe infections, leading them to remain undiagnosed for years.
- Misdiagnosis: Symptoms often mimic common pediatric infections, causing delays in genetic confirmation.
- Geographic Variability: Prevalence rates can appear higher in regions with higher rates of consanguineous marriage, as these populations see a higher frequency of autosomal recessive mutations.
