Background:
EIF1AY is one of the genes essential for normal spermatogenesis and is located in azoospermic factors region.
Objective:
The present study was designed to investigate the EIF1AY gene nucleotide variations, and correlate it with spermatogenic maturation arrest and azoospermia in Iranian population.
Methods:
A total number of 30 Iranian idiopathic non-obstructive azoospermic patients were selected as case group and 30 fertile men served as a control group who had at least 1 child. Nucleotide variation was analyzed in exon 3 and exon 5 in EIF1AY gene of both groups. DNA extraction from peripheral blood samples of selected individuals was done followed by amplification by PCR and sequencing with Sangar method.
Results:
Totally 3 single nucleotide variations were identified: one in the intronic region of exon 3, next one in non-coding transcript exon variant (rs13447352) and the third one in the exonic region of exon 5, all were registered in NCBI-Gene database.
Conclusion:
There was no statistically significant difference in the incidence of nucleotide variation between 2 study populations (p > 0.05). Further studies are required to specify the effects of Y: T20588295G variation on modification of protein structure, as well as the expression pattern of the gene and its association with azoospermia.
