Biomarkers and Genetic Modulators of Cerebral Vasculopathy in Sub-Saharan Ances...
Silva, M; Vargas, S; Coelho, A; Ferreira, E; Mendonça, J; Vieira, L; Maia, R; Dias, A; Ferreira, T; Morais, A; Soares, IM; Lavinha, J; Silva, RWe investigated biomarkers and genetic modulators of the cerebral vasculopathy (CV) subphenotype in pediatric sickle cell anemia (SCA) patients of sub-Saharan African ancestry. We found that one VCAM1 promoter haplotype (haplotype 7) and VCAM1 single nucleotide variant rs1409419_T were associated with stroke events, stroke risk, as measured by time-averaged mean of maximum velocity in the middle cerebral artery...
Genetic Modulators of Fetal Hemoglobin Expression and Ischemic Stroke Occurrenc...
Nicolau, M; Vargas, S; Silva, M; Coelho, A; Ferreira, E; Mendonça, J; Vieira, L; Kjöllerström, P; Maia, R; Silva, R; Dias, A; Ferreira, T; Morais, ASickle cell anemia (SCA) is an autosomal recessive monogenic disease with significant clinical variability. Cerebrovascular disease, particularly ischemic stroke, is one of the most severe complications of SCA in children. This study aimed to investigate the influence of genetic variants on the levels of fetal hemoglobin (Hb F) and biochemical parameters related with chronic hemolysis, as well as on ischemic st...
