Predicting the effects of frameshifting indels

Table 2 Observed fractions for the net size of two nearby indels

	Fraction of two indels in 200-bp intron that have net size divisible by 3 (control)	Fraction of two indels in the same exon that have net size divisible by 3	Enrichment (exon fraction/intron fraction)
Cow	0.45	0.77	1.71
Dog	0.47	0.78	1.64
Horse	0.49	0.66	1.33
Rat	0.46	0.87	1.92

All enrichment ratios are statistically significant (P < 0.001) by Fisher's exact test.
