Abstract
Ischemic stroke occurs due to the formation of thrombus or embolism within the arteries
due to platelet aggregation. Aspirin therapy is used for the prevention of secondary
stroke. The variant of UGT1A6 (Ser7Ala) gene has been found to be associated with
ischemic stroke as well as aspirin resistance. We aim to study the demographic profile
of ischemic stroke patients from Malwa region of Punjab and to evaluate the frequency
of UGT1A6*2 Ser7Ala polymorphism and correlate it with aspirin resistance and ADRs
(if any). We collected 30 samples from confirmed ischemic stroke patients from Guru
Gobind Singh Medical College and Hospital in Malwa region of Punjab. DNA was
isolated from blood and PCR- RFLP technique was used to evaluate the UGT1A6 gene
variant in the patients. mRS value was used to classify patients as responders or nonresponders.
24 patients had TT genotype and 6 patients were found to bear TG
genotype. 90% of patients were aspirin responders and 10% were aspirin nonresponders.
Since the sample size was too low to identify significant associations, a
large number of samples should be screened before coming to a conclusion. However,
this preliminary study indicates that UGT1A6*2 (Ser7Ala) variant of UGT1A6 gene
might be a risk factor for aspirin resistance in the studied group.
