Examples of isoform switching (differential splice variant usage) at different ages. The relative abundance is given as the FPKM and the age axis is in months. Error bars represent the standard deviation. a Apbb1—Statistically significant differential splice variant usage between 6- vs. 28-month-olds and 12- vs. 28-month-olds. b Bend6—statistically significant differential splice variant usage between 6- vs. 12-month-olds and 12- vs. 28-month-olds. c Mapk9—statistically significant differential splice variant usage between 6- vs. 12-month-olds and 6- vs. 28-month-olds
