Prevalence of C282Y and H63D mutations in the HFEgene in patients from São Paulo and Southern Brazil

Prevalência das mutações C282Y e H63D no gene HFEem pacientes de São Paulo e do Sul do Brasil

ABSTRACT

Hereditary hemochromatosis (HH) is an autosomal recessive disorder caused by mutations in the HFE gene; it is characterized by the risk of iron overload. C282Y and H63D are the most associated mutations in HH. This study aimed to determine the frequency of mutations in the south of Brazil and São Paulo. It used the real-time polymerase chain reaction (PCR) technique and the results collected from Genolab data. In 90 individuals, 46.67% had at least one of the mutations for HH. There is a high prevalence of these mutations in both populations, therefore searching for patients under clinical suspicion is recommended.

Key words:
polymorphism single nucleotide; real-time polymerase chain reaction; hemochromatosis
