Fluorescent in-situ hybridization and sequence-tagged sites for delineation of an X:Y translocation in a patient with secondary amenorrhoea.
We describe a phenotypically normal female with secondary amenorrhoea due to a translocation of genetic material involving the long arm of chromosome X (Xq28) and the long arm of chromosome Y (Yq11). We used fluorescent in situ hybridization to localize the breakpoint on the Xq. The Y chromosome breakpoint was identified using polymerase chain reaction (PCR) detection of sequence-tagged sites (STS) specific for interval 5 at Yq11.21. The relationship between this X:Y translocation and premature ovarian failure is discussed.
