title: Non-mosaic isodicentric X-chromosome in a patient with secondary amenorrhea.
abstract: An isodicentric X-chromosome idic(X) (pter----q26.1::q26.1----pter) was found in lymphocytes and ovarian tissue of a 40-year-old female patient with secondary amenorrhea. No mosaicism was observed. The phenotype-karyotype correlation of our case and of previously described non-mosaic cases of idic(X) (q::q) with different breakpoints is discussed.
