Figure 1. Expression of Csmd1 transcripts that contain exons 1–2 are lost; however, transcripts containing exon 70 persist, albeit at reduced levels, in KO mice.

A) Schematic of the mouse Csmd1 genomic locus and Csmd1 transcripts. Exon 1 is on the far right, and exon 70 is on the far left (adapted from UCSC Genome Bioinformatics; http://genome.ucsc.edu). B) Expression of Csmd1 transcripts that include exons 1–2. C) Expression of Csmd1 transcripts that include exon 70. * P<0.05 versus WT.
