COL1A2 gene deletion polymorphism in an Italian and an Ivorian populations.

The COL1A2 gene is one of the two genes encoding for the polypeptides of type I collagen, that represent the major constituent of skin, bone, tendons, ligaments, blood vessels, dentin, and many interstitial tissues. The COL1A2 gene deletion polymorphism has been considered as an informative anthropological marker for describing geographically distinct human populations. Aim of the present study was to investigate the genetic variability at COL1A2 locus in two populations, one belonging to Ouangolodougou (N = 133), a village placed in Northern Ivory Coast, and one belonging to Lecco (N = 70), a village placed in a Northern Italy region called Lombardy.

Erythrocyte polymorphisms in five ethnic groups of Northern Côte d'Ivoire.

Distribution of some erythrocyte polymorphisms was investigated in five Northern Côte d'Ivoire ethnic groups. For the ABO blood group system, the frequencies of alleles p, q and r were 0.119, 0.

DAT1 VNTR polymorphisms in a European and an African population: identification of a new allele.

Polymorphism frequencies of the dopamine transporter gene (DAT1) hypervariable region have been analyzed in a sample of Italian and Ivory Coast individuals. The 3' untranslated region (UTR) of DAT1 includes a variable number of tandem repeats (VNTR) of a 40-bp monomer, ranging from 3 to 13 repeats in Caucasian and African populations. In our sample we found alleles with 3 to 16 repeats, and the most common alleles were the 10-repeat (DAT1*10) and the 9-repeat (DAT1*9) alleles.

ACE and LRPAP1 insertion-deletion polymorphisms in a northern Ivory Coast population.

The ACE and the LRPAP1 gene insertion-deletion polymorphisms were determined in 133 healthy individuals sampled from Ouangolodougou, a village located in northern Ivory Coast. No sex differences were found in ACE and LRPAP1 gene frequencies. The ACE insertion and deletion alleles had frequencies of 0.
