Summary: The protein encoded by this gene is part of the presynaptic cytoskeletal matrix, which is involved in establishing active synaptic zones and in synaptic vesicle trafficking. Variations in this gene have been associated with bipolar disorder and major depressive disorder. Two transcript variants encoding different isoforms have been found for this gene.

In an analysis comparing 1,942 cases with lifetime diagnosis of MDD and 4,565 controls, PCLO showed a genome-wide significant association with major depressive disorder at SNP (rs2715157, p = 2.91 x 10-8) and gene-based (p = 1.48 x 10-7) level.

we report an additional patient with the 7q21.11 deletion syndrome and provide evidence that haploinsufficiency for a single gene may not be the disease mechanism. In vitro studies of the interaction between PCLO and CACNA2D1 will be required to examine the hypothesis that combined haploinsufficiency for these two synaptic proteins results in neuronal dysfunction

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.
