SCN2A and measles: Feenstra et al. identified a total of six SNPs associated with FS after measles, mumps, and rubella (MMR) vaccination (IFI44L rs273259; CD46 rs1318653), or non-MMR linked FS in general (SCN1A rs6432860; SCN2A rs3769955; ANO3 rs114444506; 12q21.33 rs1110546), but they also provided evidence that the six SNPs were not associated with post-FS epilepsy [15].
