Susceptibility of CTLA-4 −1661A/G polymorphism towards severity of rheumatic heart disease

AIM: Genetic contribution in acute rheumatic fever (ARF)/rheumatic heart disease (RHD) has been suggested but not according to severity of the valve involvement. This study attempts to identify the relevance of CTLA-4 polymorphism with severity of the disease. METHODS: In a case-control design, 291...

Sumario:AIM: Genetic contribution in acute rheumatic fever (ARF)/rheumatic heart disease (RHD) has been suggested but not according to severity of the valve involvement. This study attempts to identify the relevance of CTLA-4 polymorphism with severity of the disease. METHODS: In a case-control design, 291 healthy controls and 83 patients were genotyped for association between RHD and single-nucleotide polymorphisms −1661A/G of CTLA-4. RESULTS: Segregation of patients on the basis of severity i.e., MVL (Mitral Valve Lesion) and CVL (Combined Valve Lesion) revealed that the frequency of CTLA-4 −1661G allele depleted as the disease progressed to CVL (p < 0.05). Patients in the age group of 31–45 years were significantly more susceptible (p < 0.046). Whereas, female patients were more susceptible than the male patients. CONCLUSION: Our study suggests the risk associated with decreased frequency of CTLA-4 −1661G allele in the CVL group and in females.
