Distribution of CAG repeats in LRRK2 and other Familial PD.
| Number of alleles | Mean repeat size | Median repeat size | St. Dev | Range | |
|---|---|---|---|---|---|
| Total Sample | |||||
| All repeats | 968 | 18.47 | 17 | 3.11 | 9–34 |
| Larger Repeat | 484 | 19.92 | 19 | 3.41 | 15–34 |
| Familial PD | |||||
| All repeats | 898 | 18.51 | 17 | 3.15 | 9–34 |
| Larger Repeat | 449 | 19.96 | 19 | 3.47 | 15–34 |
| LRRK2 PD | |||||
| All repeats | 70 | 18.04 | 17 | 2.57 | 10–28 |
| Larger Repeat | 35 | 19.43 | 19 | 2.59 | 17–28 |
CAG repeat size information is presented as either “All repeats” representing both alleles from each of the 484 study participants, or as “Larger Repeat”, representing only the larger of the two repeats for each of the 484 study participant.
