Supporting this hypothesis, in a cohort of 2679 MS patients (535 from the Netherlands, 826 from Sweden, and 1318 from Canada) and 3125 healthy controls (621 from the Netherlands, 997 from Sweden, and 1507 from Canada), Aulchenko and colleagues [144] further showed that the allelic variant rs10492972 C, located in the KIF1B gene, was associated with a higher risk for developing MS (p = 2.5 × 10−10) [144]. This evidence concerns the gene KIF1B and myeloid sarcoma.
