We report on a phenotypical ''male'' dysmorphic infant with a de novo
chromosomal anomaly 46,X,Yp+. Fluorescent in situ hybridisation using
chromosome paints of the Y-chromosome (pBSY) and the X chromosome (pBS
X) showed that the abnormal Y-chromosome was the result of an apparent
ly unbalanced translocation between the X and the Y chromosome. Theref
ore, the karyotype (sic).
