Repeat instability in cells with constitutive expression
| % unstable allelesa | Average change of repeat sizeb | |
|---|---|---|
| Unidirectional transcription (forward) | 40.5% | 95 |
| Unidirectional transcription (reverse) | 23.0% | 44 |
| Bidirectional transcription | 79.0%* | 165 |
aA cut-off point of ±25 repeats was used for counting as unstable.
bAmong all alleles (stable + unstable), the average change of repeat size is expressed as the number of repeats.
*P < 0.001, Chi-square test.
