description Male infertility is a multifactorial reproductive disorder. The effect of genetic factors on male infertility has been the focus of research. Although a variety of genetic techniques are applied to male infertility in clinical practice, karyotype analysis remains a powerful and inexpensive technology. Reciprocal chromosomal translocation (RCT) is closely related to male infertility, but the clinical phenotypes of RCT carriers are varied, and the underlying pathological mechanism is unclear. Some studies suggest that RCT breakpoints disrupt the structure and function of important genes responsible for spermatogenesis. Several breakpoints of chromosome 17 are related to important genes, which can lead to spermatogenic failure. This study aimed to identify the clinical features of 3 men with translocation karyotypes involving breakpoints on chromosome 17p13. Semen analysis and cytogenetic analysis were performed with informed consent. Gene ontology analysis was performed for 60 pathogenic genes on chromosome band 17p13. Cytogenetic analysis showed that the karyotypes were 46, XY, t(6;17) (p21;p13), 46,XY,t(10;17)(q11.2;p13), and 46, XY, t(17;20) (p13;q13), respectively. Relevant studies and genes on breakpoints on chromosome 17p13 were searched for using PubMed. Fourteen reported cases of the same karyotype were reviewed. The results suggest that although chromosome 17 is closely related to spermatogenic failure, the clinical phenotypes of RCT carriers with involvement of 17p13 breakpoints are varied. The important genes involved in the breakpoint were analyzed. The results of molecular functions suggested that these targets genes on chromosome band 17p13 were mostly involved in microfilament motor activity, ATPase activity. These results suggested that the translocation chromosome and breakpoint analysis should be considered in the clinical assessment of the patients. Physicians should be aware of these in genetic counseling. These breakpoints and the function of related genes require further study.
