The objective of this study was to describe the change in diagnosis and prognosis of a child with testicular dysgenesis and 46,XY karyotype after detection of a 45,X cell line and to discuss the difficulties caused by the terms mixed gonadal dysgenesis (MGD) and XY partial gonadal dysgenesis (XYPGD). One case was reported including clinical and laboratory findings of a child of 41-day-old infan...
To present the new karyotype with mixed gonadal dysgenesis, the aetiologic approach and difficulties in genetic counseling in mosaic sex chromosome disorders. We report a fourteen-year-old boy presented with slightly ambigious genitalia. Cytogenetic and fluorescence in situ hybridization investigations were carried out on his peripheral lymphocytes. As a result, three cell lines, 45,X, 46,X,idi...
Mosaicism introduces wide variability into the clinical expression of numerical and unbalanced structural chromosomal abnormalities. The phenotypic range of variability of 45,X/46,XY mosaicism extends from Turner syndrome to mixed gonadal dysgenesis to normal males. The specific phenotype is primarily dependent on the chromosomal constitution of the developing gonad. Similar phenotypic variabil...
