Notes

A common SNP only in Asian populations, this SNP and a close neighbor also in PRKCH gene, rs3783799, have been associated with higher risk for subcortical silent brain infarction, a common form of stroke. The odds ratio for carriers of a risk allele is 1.27 (CI: 1.09-1.48, p=0.0026) compared to individuals homozygous for the non-risk allele, based on studies of ~300 Japanese patients. Association of PRKCH gene with lacunar infarction in a local Chinese Han population.
