Representative FISH images for the fetus in case 2 using the DXZ1/DYZ3/D18Z1 probe set. (A, B) Interphase (A) and metaphase (B) FISH of the fetus (cultured amniocytes). Same as in Fig. 1, FISH results are consistent with XXY, and the DYZ3 signal is at the pericentromeric region of an acrocentric chromosome most consistent with 15
