An electrophoretic variant of the lactate dehydrogenase (LDH)-B(H) subunit was discovered in a patient with diabetes mellitus. His LDH activity in serum was slightly lower than normal and the LDH isozyme pattern showed an abnormal migration indicating an LDH-B subunit variant of the fast type. The L

โฆ Synopsis
A new electrophoretic variant of the lactate dehydrogenase B subunit was found in the erythrocytes of the COP strain of the rat. The location of the band after the electrophoresis suggested a product of the structural gene for the B subunit. Two alleles that regulated the high amount (Ldh-2a) or the low amount (Ldh-2b) of the B subunit were found and segregated in Mendelian fashion. The activity was regulated by the closely linked (less than 1 cM) regulatory gene Ldr-1.

The newt, Triturus viridescens, shows a polymorphism for the genes controlling the synthesis of the enzyme lactate dehydrogenase (LDH). Homozygotes have either of two electrophoretically fast migrating bands. In heterozygotes, the isozymes present in both homozygote classes appear along with three a
The amount of lactate dehydrogenase subunit A in rat serum is under the control of the lactate dehydrogenase regulatory gene Ldr-1, and it is determined by two alleles, Ldr-1a (high) and Ldr-1b (low). Sex and LDH-A level segregate independently, so the Ldr-1 gene is autosomal. The genes for albino,
