We identified ten AJ enriched CD risk alleles (p<0.005): the previously published risk haplotypes in LRRK2 and NOD2 (LRRK2: p.N2081D; NOD2: p.N852S, p.G908R, p.M863V+p.fs1007insC)[29,30], in addition to newly implicated alleles (NOD2: p.A612T, p = 2.8x10-9; c.74-7T>A, p = 1.4x10-4; p.L248R, p = 6.4x10-4; p.D357A, p = 0.0011; LRRK2: p.G2019S, p = 0.0014, a Parkinson’s disease risk allele[31]). The gene discussed is LRRK2; the disease is Parkinson disease.
