| Country | Number of families | Number of relatives1 | Estimated number of monoallelic MUTYH mutation carriers2 |
|---|---|---|---|
| Canada | 67 | 946 | 404 |
| USA | 56 | 778 | 275 |

1
Total number of first- and second-degree relatives (probands were excluded).
2
Total number of monoallelic MUTYH mutation carriers in each family was estimated by summing the number of known carriers and the carrier probabilities of the ungenotyped relatives.
