Summary: The protein encoded by this gene is an enzyme that phosphorylates diacylglycerol, converting it to phosphatidic acid. The encoded protein is a membrane protein and is inhibited by hydrogen peroxide. Variations in this gene have been associated with hypospadias. [provided by RefSeq, Mar 2011]

What's a GeneRIF?

Five DGKK variants previously reported as associated with hypospadias were identified in the genotype data. None of the variants were associated with second- or third-degree hypospadias (range of odds ratios = 0.7-0.9, all p > .05). None of the variants were associated with second- or third-degree hypospadias (range of odds ratios = 0.7-0.9, all p > .05).
Title: The role of genetic variation in DGKK on moderate and severe hypospadias.
This study successfully implicated DGKK variants in hypospadias risk among a Han Chinese population, especially for mild/moderate cases. Severe forms of hypospadias are likely due to other genetic factors
Title: Association between diacylglycerol kinase kappa variants and hypospadias susceptibility in a Han Chinese population.
Our study provides strong evidence of an association between DGKK nucleotide variants, haplotypes and hypospadias susceptibility.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
