comparison of the um-ec-2 karyotype to that of um-ec-1 ( a previously described line from a different patient with endometrial carcinoma ) revealed that the two lines share eight very similar chromosome changes , which include loss of most of chromosome 4 , breakpoints affecting proximal bands on 8p , loss of most of 9q , a breakpoint at 12q22 , loss of 13q , breakpoints in proximal bands on 18q , and a breakpoint at 22p11 .
