Plasma protein and red cell enzyme groups in Galicia (north west Spain).

Galactose-1-phosphate uridyl transferase (GALT), esterase D (EsD), and plasminogen (PLG) phenotypes were determined by isoelectric focusing in thin-layer polyacrylamide gels (PAGIF) in a random sample from Galicia. Haptoglobins (Hp) were determined by conventional electrophoresis. The following gene frequencies were observed: for GALT: GALTN: 0.930; GALTD1: 0.044; GALTD2: 0.025; for EsD: EsD1: 0.874; EsD2: 0.104; EsD3: 0.021; for PLG: PLG1: 0.800; PLG2: 0.199; for Hp: Hp1: 0.426; Hp2: 0.573. Population data results of all electrophoretic markers typed until now in Galician population are also included.
