Imbalances of gamma globulin subgroups and gene defects in patients with primary hypogammaglobulinemia

Abstract

Analysis of immunoglobulin classes, γG subgroups, and Gm genetic markers from 59 patients with various types of immune deficiencies was undertaken to assess the function of the several cistrons concerned with synthesis of gamma globulins. 13 patients including two sibling pairs were found to have γG subgroup imbalances. All of these patients had non sex-linked disease. 11 of the 13 had preponderance of the γG3 subgroup. In most instances of γG3 preponderance it was the Gm(b) type of γG3 that was selectively retained; the Gm(g) type, controlled by the allelic gene was markedly depressed but not absent in the cases where it could be studied. Other imbalances, either seen concomitantly with γG3 preponderance or independently, included predominance of the γG2 subgroup and selective absence of single γG subgroups.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.

Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
