First report of PURA syndrome in a Colombian patient with de novo missense variant c.692T>C (p.Phe231Ser).

We present the first documented case of PURA syndrome in Colombia. This rare neurological disease results from mutations in the PURA gene located on chromosome 5, leading to haploinsufficiency of the PUR-α protein. This protein is essential for early brain development and neuronal function.

Molecular characterization of mucopolysaccharidosis type IVA patients in the Andean region of Colombia.

Colombia has a high prevalence of mucopolysaccharidosis (MPS) type IVA. Nevertheless, data regarding the mutation spectrum for MPS IVA in this population have not been completely characterized. Forty-seven families and 53 patients from seven different Colombian regions were tested for MPS IVA mutations.

Population data on 15 autosomal STRs in a sample from Colombia.

We present population genetic data of 15 STRs (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, PENTA D, PENTA E, TH01, TPOX and VWA) obtained from a sample of 617 unrelated individuals from Colombia. Deviations from Hardy-Weinberg equilibrium were assessed and allele frequencies and parameters of forensic interest for each STR were calculated. The combined power of exclusion (PE) and the combined power of discrimination (PD) for the 15 tested STR loci were 0, 99999895 and more than 0, 9999999, respectively.

The genetic male component of two South-Western Colombian populations.

In the recent history of Colombia, two factors have contributed to change the population structure, the Spanish conquest and the slave trading promoted principally by Portugal, England and Spain. As a consequence the native population of Colombia has been reduced and mixed with the European and African arriving groups. To assess the male ancestry of the Cauca population, we have examined the frequency of the major Y-chromosome lineages by typing 30 Y-SNPs in two populations from this region: 105 Afro-Colombian individuals and 110 Caucasian-Mestizo individuals.

Autosomal microsatellite data from Northwestern Colombia.

Allele frequencies and some forensic parameters for 12 autosomal microsatellites (CSF1PO, TPOX, THO1, VWA, D16S539, D7S820, D13S317, D5S818, F13A1, FESFPS, F13B, LPL) were estimated from three departments from Northwestern Colombia. The total number of samples analysed was 1045 individuals. Comparative analysis among the three studied departments and with other published Colombian populations were also performed and discussed.

Nineteen autosomal microsatellite data from Antioquia (Colombia).

Allele frequencies for 19 autosomal STRs (F13A01, FESFPS, F13B, LPL, D5S818, D7S820, THO1, TPOX, VWA31, CSF1P0, D16S539, D13S317, D3S1358, D8S1179, FGA, PENTA D, PENTA E, D21S11, D18S51) were estimated from a sample between 364 and 400 unrelated individuals living in the northern department of Antioquia.

Genetic data on eight STRs (D5S818, D7S820, F13B, LPL, TH01, TPOX, VWA31, CSF1PO) from a Colombian population.

Allele frequencies for eight short tandem repeats (STRs) (D5S818, D7S820, F13B, LPL, TH01, TPOX, VWA31 and CSF1PO) were estimated from a sample of 155 unrelated individuals living in different departments of the southwest of Colombia, Caquetá, Cauca, Huila, Nariño, Putumayo and Cauca Valley.
