Genetic polymorphisms of <Emphasis Type="Italic">T-1131C APOA5</Emphasis> and <Emphasis Type="Italic">ALOX5AP SG13S114</Emphasis> with the susceptibility of ischaemic stroke in Morocco

Ischaemic stroke is a multifactorial disease. Genetic polymorphisms involved in lipid, inflammatory and thrombotic metabolisms play an important role in the development of ischaemic stroke. The present study aimed to assess the relationship between T1131C APOA5 and SG13S114 ALOX5AP polymorphisms and the risk of ischemic stroke in 175 cases and 201 controls. Genotyping was performed by high resolution melting and polymerase chain reaction restriction fragment length polymorphism methods. In the case of T-1131C APOA5, a modest risk of ischaemic stroke was noticed with CC (OR: 2.86; 95% CI = 1.24–6.58; Pc = 0.039) and C allele (OR: 1.54; 95% CI = 1.01–2.33; Pc = 0.014). For SG13S114ALOX5AP, a significant association was observed among subjects with TT (OR: 2.57; 95% CI =1.49–4.83; Pc = 0.009) and T allele (OR: 1.59; 95% CI = 1.16–2.19; Pc = 0.008). According to the risk factors of ischaemic stroke, a positive correlation was observed only between SG13S114 variant of ALOX5AP gene and hypertension (Pc = 0.026). Despite lower sample size, T-1131C APOA5 and SG13S114 variants could be considered an independent genetic risk factor of ischaemic stroke in Moroccan population.
