Abstract:
Objective To study the relationship between diabetic retinopathy(DR) and Landsteiner-Wiener,Indian blood group genes.Methods Peripheral blood samples were collected from 50 DR patients,and 160 unrelated volunteer blood donors(the control).CDNA,including LW gene generated by reverse transcription polymerase chain reaction(RT-PCR),was subjected to sequence analysis,and the genomic DNAs,extracted from each sample,were sequenced directly for LW gene and IN gene.Woolf method was used for calculating relative risk(RR).Results In the 160 control samples,there was A at the nt380 locus in Exon1 of the LW gene,which were genotyped as LWa;and there was G at the nt252 locus in Exon2 of the IN gene,which were genotyped as INb.All the 53 samples from DR patients were LWa homozygous genotypes and all INb homozygous genotypes.Conclusion These two candidate genes are not associated with the incidence of DR.
