✦ Synopsis

Cytogenetic and molecular analyses of three dicentric X chromosomes were performed in an attempt to identify the parental origin and mechanism of formation of the aberrant chromosomes. Results indicate that, in these three cases, the dicentric chromosomes were formed by chromatid breakage and reunion of sister chromatids at the breakpoint. In two cases the abnormal chromosomes were paternal in origin; in the third case the dicentric originated from the maternal X chromosome.

Five polymorphic index markers were analyzed by polymerase chain reaction (PCR) to ascertain the parental origin of the extra X chromosomes in seven polysomic cases (one 49,XXXXX, three 49,XXXXY, two 48,XXXY, and one 48,XXYY). All four X chromosomes in 49, X polysomies were maternal in origin and th
