A New Hæmagglutinating Substance in the Gm System, Anti-Gm

Abstract

A SYSTEM of inherited serum groups has been described by Grubb and Laurell1. Sera from certain patients with rheumatoid arthritis agglutinated Rh-positive red cells which had been coated with selected incomplete anti-D. The agglutination was inhibited by sera from about 60 per cent of normal individuals, who were said to be Gm(a+) because the inhibiting substance was located in the gamma-globulin fraction of serum. This substance was inheritable, determined by the gene Gma, which expressed itself in single or double dose. The corresponding allele was called Gm.
