Copy number variant plot (CNV) plot across Phactr1 locus based on genome sequencing data from BCCAS mice with different vascular phenotypes: three BCCAS mice with two very prominent PcomAs and ECA retrograde flow, which did not develop any ischemic lesion detectable on T2-weighted MRI both 1 and 7 days post-surgery (Fig. 2BI) and 3 BCCAS mice with no PcomAs and ECA retrograde flow,which developed severe hemispheric lesions and died within a few hours-one day post-surgery (Fig. 2BII).
