Objective:
The PDLIM5 gene is known to interact specifically with the N-type calcium channel alpha-1B subunit and protein kinase C epsilon and is critical for rapid, efficient potentiation of the calcium channel activation by protein kinase C in neurons. Increasing amounts of data suggested that PDLIM5 might be involved in the pathophysiology of major depressive disorder (MDD). The aim of this study was to examine whether genetic variations in the human PDLIM5 gene might contribute to the liability to develop MDD.
Method:
We undertook a gene-based association analysis of single nucleotide polymorphisms (SNPs). Three SNPs (rs10008257, rs2433320 and rs2452600) were identified in the PDLIM5 gene and genotyped in patients diagnosed with recurrent MDD and in matched control subjects.
Results:
We observed significant allele (p = 0.007) and genotype (p = 0.007) association with rs2433320, and the G allele of rs2433320 was significantly overrepresented in control subjects in comparison with MDD patients.
Conclusion:
These results support the hypothesis of a protective effect for the G allele of rs2433320 in the PDLIM5 gene in recurrent MDD.
