Glutamate-pyruvate transaminase (GPT) variant found in a disputed paternity case

GPT variants, GPT2C-1 and GPT2A-2C, were found in samples from a mother and her child, respectively, in a disputed paternity case. The phenotype GPT 2C-1 was determined by polyacrylamide gel electrophoresis performed at alkaline pH and acidic pH; this is probably the first GPT*2C-1 detected in Japanese. It was considered that the GPT 2C allele in this family was inherited in a manner of autosomal codominant transmission.
