Abstract:
OBJECTIVETo assess the association between gene polymorphisms and memory function through a genome-wide association study (GWAS) of schizophrenia and control group. Memory cognition was used as a quantitative trait (QT).
METHODSNinty-eight subjects with chronic schizophrenia and 60 matched controls were genotyped with HumanHap660 Bead Array. The results were correlated with quantitative traits including memory and memory delay.
RESULTSFive candidate genes, including RASGRF2 (rs401758, P = 8.03×10(-5)), PLCG2 (rs7185362, P= 4.54×10(-5)), LMO1 (rs484161, P=9.80×10(-7), CSMD1 (rs2469383, P= 2.77×10(-6)) and PRKG1 (rs7898516, P=6.94×10(-5)) were associated with memory cognition deficits.
CONCLUSIONUsing memory cognition as a quantitative trait, this Genome- wide association study has identified 5 susceptibility loci. With their association with nervous system development, neuronal growth, axon guidance and plasticity, brain development, above loci may play a role in the development of memory dysfunction in schizophrenia.
