D1S80 polymorphism, including a new variant, in a population sample from Barcelona (Spain) using polymerase chain reaction.

Allele and genotype frequencies for the D1S80 (MCT118) locus have been determined in a population sample from Barcelona (Spain) using the polymerase chain reaction (PCR) amplification and nonradioactive detection. In a total of 216 unrelated individuals, 24 alleles (23 common and 1 rare variant) and 67 genotypes (64 common and 3 variants) were observed. The 216 individuals came from 162 blood samples taken for paternity studies, 16 bloodstains from forensic cases, and 38 root hairs from normal individuals.
