Journal ArticleDOI
Effect of α-thalassemia and β-globin gene cluster haplotypes on the hematological and clinical features of sickle-cell anemia in Brazil
Maria Stella Figueiredo,José Kerbauy,Marilda Souza Goncalves,V. R. Arruda,Sto Saad,Maria de Fátima Sonati,T.A. Stoming,Fernando Ferreira Costa +7 more
TL;DR: The results indicate that the CAR haplotype may be associated with more severe disease, as in other studies.
Journal ArticleDOI
Sickle Cell Disease in a Brazilian Population from Sao Paulo: A Study of the βs Haplotypes
Marilda Souza Goncalves,J.F. Nechtman,Maria Stella Figueiredo,José Kerbauy,V. R. Arruda,Maria de Fátima Sonati,S.O.T. Saad,Fernando Ferreira Costa,T.A. Stoming +8 more
TL;DR: In this study, the frequency of βs haplotypes in a Brazilian sickle cell disease population from Sao Paulo, Brazil is determined by analyzing sequence variations in the immediate 5’ fl.
Journal ArticleDOI
Brain Magnetic Resonance Imaging Abnormalities in Adult Patients With Sickle Cell Disease Correlation With Transcranial Doppler Findings
Gisele Sampaio Silva,Perla Vicari,Maria Stella Figueiredo,Henrique Carrete,Marcos Hideki Idagawa,Ayrton Roberto Massaro +5 more
TL;DR: The frequency of brain imaging abnormalities detected by MRI/MR angiography in adults with SCD was higher than that described for children and transcranial Doppler velocities in adult patients with intracranial stenoses were lower than those described for the pediatric population withSCD.
Journal ArticleDOI
Clinical, hematological, and molecular characterization of sickle cell anemia pediatric patients from two different cities in Brazil
Isa Menezes Lyra,Marilda Souza Goncalves,Marilda Souza Goncalves,Josefina Aparecida Pellegrini Braga,Maria de Fátima Malvar Gesteira,Maria Helena Carvalho,Sara Teresinha Olalla Saad,Maria Stella Figueiredo,Fernando Ferreira Costa +8 more
TL;DR: Data suggest a milder phenotype among patients in Salvador, possibly due to genetic, environmental, and socioeconomic factors, and further studies are needed to elucidate modulating factors and phenotype association.
Journal ArticleDOI
Hereditary hemochromatosis: mutations in genes involved in iron homeostasis in Brazilian patients.
Paulo Caleb Junior Lima Santos,Rodolfo D. Cançado,Alexandre C. Pereira,Isolmar T. Schettert,Renata Alonso Gadi Soares,Regina Alexandre Pagliusi,Rosario Dominguez Crespo Hirata,Mario Hiroyuki Hirata,Ana Claudia Teixeira,Maria Stella Figueiredo,Carlos S. Chiattone,José Eduardo Krieger,Elvira Maria Guerra-Shinohara +12 more
TL;DR: The low rate homozygous p.C282Y mutation in Brazil is suggestive that mutations in non-HFE genes may be linked to HH phenotype, and exon-by-exon DNA sequences of HFE, HJV, HAMP, TFR2 and SLC40A1 genes are screened to characterize the molecular basis of HH.
