Abstract

Introduction: Thymic stromal lymphopoietin (TSLP) has been linked as a susceptibility gene for the development of allergic diseases. It is known that the population of Cartagena is a triethnic mix, in which the component of African ancestry was significantly associated with risk of asthma and high total serum IgE levels. This component comes from African slaves brought into the continent and settled in“palenques”, one of them is San Basilio de Palenque, in the Colombian Caribbean Coast.

Objective: To analyze the distribution of single nucleotide polymorphisms (SNP) rs1837253,rs17551370 and rs2289276 located in TSLP gene, in the African-descendent population of San Basilio de Palenque.

Materials and methods: By real time-PCR and probes TaqMan SNP Genotyping™, we genotyped three polymorphisms in 80 individuals of African-descent aged 5 to 18 years of age.

Results: The frequency of the rs1837253 allele T was 41.9%, for the allele A, 14.3% for rs17551370,and 22.5% for the allele T of rs2289276. The rs17551370 and rs2289276 distribution remained in Hardy-Weinberg genetic equilibrium. The allele frequency of each SNP did not show statistically significant differences with those reported for other African and African-descendent populations.

Conclusion: The three polymorphisms in the TSLP were present in the sample population of San Basilio de Palenque and its distribution is similar to that reported for African populations and African ancestry in America.
