Abstract：
:Serum levels of IgA1 and IgA2 were measured by solid phase radioimmunoassay in samples from 110 children between 3 months and 10 years of age. Both IgA1 and IgA2 were detectable in all samples, and both IgA1 and IgA2 increased with increasing age. The percent of total serum IgA that was IgA2 did not change with age and was the same in samples from children (15.05 +/- 10.2%) as in samples from adults (15.86 +/- 7.98%). The proportion of serum IgA that was IgA2 was much less variable within sibships than within the group at large (P less than 0.005). In the 16 patients with IgA deficiency, the proportion of serum IgA that was IgA1 or IgA2 was highly variable. IgA2 constituted more than 50% of the IgA in 5 patients and less than 7% of the IgA in an additional 5 patients. These findings suggest that regulation of serum concentrations of IgA1 and IgA2 is complex and influenced by genetic factors and probably other unidentified factors.
