draft a statement to illustrate igan is more common in age 20-40

Research studies have shown that IgAN, also known as IgA nephropathy, is more commonly diagnosed among individuals aged 20-40 years old. This age range accounts for the majority of IgAN cases worldwide. The reasons for this trend are not yet fully understood, but it may be due to a combination of genetic and environmental factors. Nevertheless, it is crucial to raise awareness about the prevalence of IgAN among young adults, and for healthcare providers to remain vigilant in identifying and managing this condition in this age group.
