“…When comparing allele frequency data from São Tomé e Príncipe to other 4 African continental mainland populations from Cabinda (Beleza et al, 2004), Mozambique , Equatorial Guinea (Alves et al, 2005) and Republic of Guinea-Bissau (Gonçalves et al, 2002) several significant differences were found (exact P<0.05) but applying the Bonferroni correction (SISA) the significance level lowered to 0.0127 and significant values were only found with Mozambique at loci TH01 (exact P=0.007±0.001) and TPOX (exact P=0.000±0.000), and with Guinea-Bissau at loci TH01 (exact P=0.000), which seems to reflect the colonization history of São Tomé e Príncipe that received most part of slaves from the West African coast neighboring the archipelago. A neighbor-joining tree was constructed based upon the 6 STR allele frequencies in our sampled population and from populations from Central Portugal (Manco et al, 2007(Manco et al, /2008, North Portugal (Pinheiro et al, 2005), Madeira , Azores (Velosa et al, 2002), Cabinda (Beleza et al, 2004), Mozambique , Equatorial Guinea (Alves et al, 2005) and Guinea-Bissau (Gonçalves et al, 2002) (Figure 1).…”

“…Allele frequencies from Cabinda (Beleza et al, 2004), Mozambique , Equatorial Guinea (Alves et al, 2005) and Guinea-Bissau (Gonçalves et al, 2002) were used for genetic differentiation tests with São Tomé e Principe population sample, applying the Bonferroni correction for multiple tests (Hochberg, 1988). A neighbor-joining tree was constructed using the PHYLIP3.5c software package (Felsenstein, 1993) based on Reynolds Genetic distance (Reynolds et al, 1983) with a bootstrap of 10000 resamples, using population data from different Portuguese regions, Central Portugal (Manco et al 2007(Manco et al -2008, North Portugal (Pinheiro et al, 2005), Madeira , Azores (Velosa et al, 2002), and from other African populations, Cabinda (Beleza et al, 2004), Mozambique , Equatorial Guinea (Alves et al, 2005) and Guinea-Bissau (Gonçalves et al, 2002).…”

Resumo As frequências alélicas de seis marcadores autossómicos do tipo short tandem repeat (STR) (TH01, TPOX, CSF1PO, D13S317, D7S820 e D16S539) foram estimadas numa amostra populacional (N=53-85) de São Tomé e Príncipe (África Ocidental). Não foram encontrados desvios significativos ao equilíbrio de HardyWeinberg em qualquer dos loci. A distribuição de frequências e valores de heterozigotia são semelhantes aos encontrados noutras populações Africanas sub-Saarianas.Palavras-chave São Tomé e Príncipe; short tandem repeats (STRs); genética populacional.Abstract Allele frequencies of six autosomal short tandem repeat (STR) markers (TH01, TPOX, CSF1PO, D13S317, D7S820 and D16S539) were estimated in a population sample (N=53-85) of unrelated individuals from São Tomé e Principe (West Africa). No deviations from Hardy-Weinberg equilibrium were observed for all loci. Allele frequency distribution and heterozygosity values were similar with those from other sub-Saharan African populations.

“…The Identifiler system includes the 13 CODIS along with 2 additional loci, D2S1338 and D19S433, which are used in most forensic labs to determine parentage (Collins et al, 2004). It has been shown that the D6S1043 and D12S391 loci are of high value in forensic parentage testing (Tong et al, 2010), and Penta D and Penta E are often used in forensic cases as non-CODIS markers (Salem et al, 2003;Alves et al, 2005;Chouery et al, 2010).…”

ABSTRACT. The aim of this study was to evaluate whether the Goldeneye 20A system (containing 19 short tandem repeats) can avert the shortage of duo parentage tests. Among routine cases typed by the Identifiler system, we identified 42 motherless cases, 2 fatherless cases, and 34 trio cases containing 1 locus mismatch and 4 motherless cases with 2 locus mismatches. One true trio case was rejected by fatherhood testing because of the omission of the mother's genotype and because the genotype of the putative father matched that of the child. All of the cases were retyped by the Goldeneye 20A system with the mother's or father's sample. In total, 39 motherless cases were verified by one mutation, 3 motherless cases were rejected for paternity, and 4 motherless cases with 2 locus mismatches were ruled out by fatherhood testing. After adding the father's genotype, 1 motherless case was confirmed by a single-locus mutation, whereas another case was rejected by motherhood testing. The mutation and exclusion rates detected with the Goldeneye 20A system accorded with the corresponding rates identified in the Identifiler system. The trio case also rejected fatherhood without the mother's genotype, and we found only 2 locus mismatches. Neither the Identifiler system nor the Goldeneye 20A system compensates for the absence of genetic information from the mother or father.
