This is most frequently diagnosed in adults aged 20–40 years. However, about 28% of subjects are given a diagnosis before age of 21 years. Median age at characteristic symptom onset was 24 years for males and 27 years for females, but males were diagnosed with common variable immunodeficiency earlier at a median age of 30 years than females at a median age of 33.5 years.
