Figure 1: Partial karyotype of the proband and the father. Father: Translocation of segment on chr. 3 distal to 3p22 onto chr. 6 at band 6p22.1, translocation of the segment on chr. 6 distal to 6p22.1 onto chr. 11 at 11p15.2 and translocation of the segment on chromosome 11 distal to 11q15.2 onto chr. 3 at 3p22. Proband: Direct transmission of derivative chr. 11 containing the segment of chr. 6 from father resulting in unbalanced karyotype - partial 6p22.1 - pter and partial Monosomy 11p15.2-11pter
