ABSTRACT
<p><b>OBJECTIVE</b>To investigate the role of single nucleotide polymorphisms of the gene of diacylglycerol kinase κ (DGKK) in hypospadias in Chinese children.</p><p><b>METHODS</b>We performed direct sequencing on 2 hypospadias-related candidate single nucleotide polymorphisms of the DGKK gene (rs1934179 and rs7063116, never previously reported in the Chinese population) from 300 children with sporadic hypospadias and 200 healthy controls, and compared the results between the two groups.</p><p><b>RESULTS</b>The mutation frequencies of rs1934179 and rs7063116 were 5.0% (15/300) and 5.67% (17/300) respectively in the hypospadias patients, significantly higher than 1.5% (3/200) and 2.0% (4/200) in the normal controls (P <0.05). The mutation frequencies of rs1934179 and rs7063116 in the cases of distal and middle hypospadias were also remarkably higher (6.5%, [13/200] and 7.5% [15/200], P <0.05), but those in the proximal cases (both 2.0% [2/100]) showed no statistically significant difference from the control (P >0.05).</p><p><b>CONCLUSION</b>The polymorphisms of the DGKK gene may be associated with hypospadias, particularly distal and middle hypospadias, in Chinese children.</p>
