Most studies that looked at angiosarcoma cytogenetics identified complex cytogenetics.12, 13, 168 Aberrations included gain or loss of entire chromosomes as well as partial chromosomes; interestingly, 2 of 8 cases in one series had duplication of the region on chromosome 4q that contains KIT and VEGFR2. 12 A fusion of the Nucleoporin 160 kDa gene NUP160 and Solute Carrier Family 43, Member 3 gene SLC43A3, both on chromosome 11, was recently found in both primary angiosarcoma specimens and an established angiosarcoma cell line.169. Here, SLC43A3 is linked to angiosarcoma.
