Phosphoglucomutase (PGM1) subtypes in a Finnish population determined by isoelectric focusing in agarose gel.
The red cell enzyme phosphoglucomutase first locus (PGM1) phenotypes of 639 adult Finns were determined by isoelectric focusing in agarose gel. All the ten commonly occurring phenotypes were detected and the frequencies of the four alleles at the PGM1 locus were as follows: PGMa11 = 0.5313, PGMa21 = 0.1800, PGMa31 = 0.2199 and PGMa41 = 0.0689. The PGM1 phenotypes of 221 mothers with 228 offspring were in accordance with autosomal codominant inheritance.
