Abstract

Although sickle cell anemia results from homozygosity for a single mutation at position 6 of gamma-hemoglobin locus, this disease presents high heterogenity in phenotype, so that different patients may have significantly different clinical outcomes. Virtually all organs may be affected by vascular occlusion, with emphasis on the Central Nervous System (CNS), where are observed transient ischemic attacks, stroke and cerebral hemorrhage, which affect approximately 25% of patients with SCA. Neurological complications are serious and can be fatal in up to 15% of cases. Early identification of patients with sickle cell anemia, susceptible to stroke (CVA) could reduce the risk, possibly preventing the recurrence of heart attacks and potentially reduce their incidence. Therefore, studies aimed at identifying new risk groups for development of stroke in sickle cell patients would be essential to optimize the clinical management of this disease, one of these pathways the molecular approach of this group of patients. Thus, we propose to investigate the presence of copy number variation in allele or "Copy Number Variation" (CNV), using high density microarray in order to identify genomic regions potentially involved in the increased risk of stroke in sickle cell patients.
