Implication of rs1026611 in the MCP-1 Gene and V64I of CCR2 in Stroke among SCA Tunisian Patients

Stroke is a devastating and potentially fatal complication to sickle cell Anemia. Strokes are difficult to explain on the basis of the central pathological process in SCA, namely the occlusion of small vessels by deformed sickled cells. We examined whether Single Nucleotide Polymorphism (SNP) variants in the MCP-1 or CCR2 genes independently or in combination are associated with occurrence of Cerebrovascular Accidents (AVC) in SCA Tunisian patients. Material and methods: 100 SCA patients among whom 19 have AVC were enrolled in this study. Clinical diagnosis of stroke was performed by the use of Transcranial Doppler ultrasonography (TCD). The genotyping of rs1026611 in the MCP-1 gene and V64I of CCR2 was performed using PCR/RFLP. Results: Our findings showed no association of the polymorphisms studied with occurrence of AVC in SCA Tunisian patients.
