Dinucleotide repeat polymorphism in a gene on chromosome 20 encoding a G-protein coupled receptor (D20S32e).

MendeUan Inheritance: Co-dominant inheritance was observed in a five-generation pedigree in which 113 individuals were typed. Other Comments: The PCR was performed using P-labeled GPR 112-1 and unlabeled GPR 112-2 for 30 cycles: denaturation at 94°C for 1 min; annealing for 55°C for 1.5 min; and extension at 72°C for 3 min. The PCR products were analyzed on a 5% denaturing polyacrylamide gel (Figure).
