A metaphase spread and hexavalent configuration. (a) A metaphase spread from the patient hybridized with whole chromosome painting probes for chromosomes 1 (green), 3 (red), and 6 (blue); (b) a putative hexavalent configuration during chromosome synapsis at pachytene-stage of meiotic division of the 4-breakpoint 46,XY,t(1;3;6) complex chromosome rearrangement carrier.

Single spermatozoa array CGH analysis of the 4-breakpoint 46,XY,t(1;3;6) complex chromosome rearrangement carrier. A gain of the chromosome or its part is indicated by shifting above the green horizontal line and a loss of the chromosome or its part by shifting below the red horizontal line. (a) A normal or balanced sperm bearing X chromosome (gain of X, loss of Y chromosome compared with 46,XY reference DNA); (b) a normal or balanced sperm bearing Y chromosome (loss of X, gain of Y chromosome compared with 46,XY reference DNA); (c) the unbalanced sperm [23,X,+der(1),−6] derived from 3:3 segregation; (d) the unbalanced sperm [22,Y,−1,der(3),der(6)] derived from 4:2 segregation; (e) the unbalanced sperm [23,X,−3,+der(6)] derived from 3:3 segregation, notice the small gain in chr. 1 (arrow) due to the presence of normal chromosome 1 and der(6) with insertion of a short region of chr. 1; (f) the unbalanced sperm [23,X,der(1),der(3),−6,+8] derived from 4:2 segregation, notice the small loss in chr. 1 and the additional gain of chr. 8 (arrows). The loss in chr. 1 is ascribed to the presence of der(1) and der(3) chromosomes composed of large terminal parts of chr. 1 and absence of der(6) with insertion of a short region of chr. 1; (g) the unbalanced sperm [23,X,−1,+der(3),der(6)] derived from 3:3 segregation, notice additional structural abnormality in chr. 7 (arrow); (h) the unbalanced sperm [24,X,der(3),+der(3)] derived from 4:2 segregation and a crossing-over between normal and derivative chr. 3, notice three copies of part of chr. 1 (arrow).
