PPP2R2B and spinocerebellar ataxia type 12: rs79727797 is significantly associated only with expression of the nearby gene PPP2R2B (expansions in which cause SCA12) in eQTLGen (p = 1.13 × 10−16), with the A allele that is associated with later onset being associated with increased expression of PPP2R2B. However, there are several SNVs more significantly associated with PPP2R2B expression in eQTLGen, and these have only modest significance in the GeM-GWAS (p-values of ~0.07, see Supplementary Data).
