2 Figure 1 Pedigrees of Nine Unrelated IM Families
The inheritance pattern in all the families used in this study was consistent with autosomal-dominant transmission. Five families have been previously reported: IM-1,14 IM-2,15 IM-6,14 IM-7,16 IM-8.17 Asterisk indicates that these samples were whole-exome sequenced.

4 Figure 3 Tumor Cell Lines Derived from Affected Individuals Demonstrate a Myofibroblastic Phenotype Vimentin (green) and a-SMA (red) staining of tumor cell lines from members of family IM-9. Cells were cultured from a soft-tissue tumor excised from an affected area on the affected individual’s back as part of their care. Three paired views at 20× (left column) and 40× (right column) are shown.
