GENE: RLS1
CYTO: 12q12-q21
DESC: Restless legs syndrome, susceptibility to, 1
SNP : rs2300478

In a genomewide association study of 393 RLS patients and 1602 controls,
Winkelmann et al. (2007) found a significant association between RLS and
dbSNP rs2300478 in the MEIS1 gene (601739). The findings were confirmed
in 2 independent replication studies of 875 and 211 patients,
respectively. Combined results of all 3 studies yielded an overall odds
ratio of 1.74 for the G allele (p = 8.08 x 10(-23)). The study also
showed evidence for an association with several SNPs within a region on
chromosome 15q that contains the LBXCOR1 (611273) and MAP2K5 (602520)
genes.
