| Frequency | ||||
|---|---|---|---|---|
| Marker* | Allele | R115G patients (n = 4) | Controls (n = 90) | p Value† |
| *Order of markers (centromere to telomere): Yorick - 41 kb - SNP SOD1 intron 1 - 2.9 kb - SNP SOD1 intron 3 - 234 kb - D21S63. †All other alleles (that is, non-7, non-A, non-C, non-4) were combined. | ||||
