(TTTA)n polymorphism of CYP19 (aromatase gene) in Euro- and Afro-Brazilians

Autor: Kátia Kvitko, Janice Corrêa de Barros Nunes, Mara Helena Hutz

Publikováno v: Genetics and Molecular Biology, Vol 27, Iss 3, Pp 335-336 (2004)

We investigated the polymorphic tetranucleotide repeat (TTTA)n located in the fourth intron of the CYP19 gene in two Brazilian populations. The frequencies of the five common alleles (A) in Euro- and Afro-Brazilians were, respectively: seven repeats

Publikováno v: Mutation Research/Genetic Toxicology and Environmental Mutagenesis. 808:38-51

Increasing evidence suggest that occupational exposure to open-cast coal mining residues like dust particles, heavy metals and Polycyclic Aromatic Hydrocarbons (PAHs) may cause a wide range of DNA damage and genomic instability that could be associat
