Introduction
Trisomy X is a chromosomal disorder affecting females, characterized by the presence of an additional X chromosome.
Overview of Trisomy Xpter Xq13
Trisomy X syndrome, or Triple X, is a medical condition where a person has an extra X chromosome in every cell of their body. Normally, girls have two X chromosomes while boys have an X and a Y. Trisomy X is a chromosomal disorder that affects females, leading to the presence of three X chromosomes instead of the typical two. This additional chromosome can result in a variety of phenotypic characteristics and clinical manifestations, ranging from mild to more severe symptoms. The condition is associated with genetic variants at Xq13 and may involve X-inactivation center abnormalities.
Cytogenetic Analysis
The cytogenetic analysis revealed a mosaic karyotype with a rearranged X chromosome, confirming the presence of Trisomy Xpter Xq13.
Revealed Mosaic Karyotype
