The highly conserved Pumilio protein plays crucial roles in fertility of many organisms acting as a repressor of translation, and causing infertility when mutated. Although one of two human Pumilio homologs, PUMILIO2 is expressed mainly in the germ line, its role in mammalian germ cell development has not been reported yet. To shed light on the role of PUMILIO2 in development of the human male germ line, we screened this gene for mutations in 137 patients presenting a variety of phenotypes with spermatogenic failure. The first variant, we identified was a single base substitution within intron 15 (IVS15 + 6G > A). This variant was found in three azoospermic males, the second allele being the wild type. However, this variant was also present among fertile males, as frequently as in the patients. Although location of IVS15 + 6G > A substitution in close proximity to the canonical donor splice site GT, indicates that its influence on splicing cannot be excluded, our preliminary cDNA analysis has not revealed evidence of a splicing abnormality of PUMILIO2 pre-mRNA carrying this variant. Nevertheless, this study provides new interesting variant containing a donor splice site variant, which can be relevant for understanding of splicing mechanism of mammalian genes. The second variant, c.774 C > T transversion (Y258Y) in exon 6 was found only in one patient, but an influence on PUMILIO2 function is not obvious. Altogether, this study shows that variation in the PUMILIO2 gene is very low and it seems improbable that mutations of this gene significantly contribute to male infertility in humans.
