HOXD13 and teratoma: Amplifications of EVX2, HOXD13, HOXD12, HOXD11, HOXD10, and HOXD9 on a 41.6 kb segment of 2q31.1 (average log2 ratio = 0.303, Fig. 2), NDUFV1 on a 2.8 kb segment of 11q13.2 (average log2 ratio = 0.685, Fig. 3), and RPL10, SNORA70, DNASE1L1, TAZ, ATP6AP1, and GDI1 on a 44.5 kb segment of chromosome Xq28 (average log2 ratio = 0.336, Fig. 4) were identified in all teratomas.
