Growth retardation.

<p>(<b>A</b>) Growth curve of +/<i>ΔEx1A</i> and wild-type littermates from 1 day to 12 weeks. The weights of wild-type littermates have been normalised to 1 at each timepoint and the weights of +/<i>ΔEx1A</i> mice have been taken as a percentage of wild-type weights. (n = 5–26). (<b>B</b>) Growth curve of PatDp(dist2)2∶2 and +/<i>ΔEx1A</i>. The weights of +/<i>ΔEx1A</i> littermates have been normalised to 1 at each timepoint and the weights of PatDp(dist2)2∶2 mice have been taken as a percentage of +/<i>Ex1A</i> weights (n = 9–12). Error bars show standard errors of the means.
