Definition
What is Tuner’s Syndrome? A genetic disorder in girls caused by a missing
or defective X (female) chromosome.
How does it Occur? The human cells have 22 pairs of chromosomes and 1
pair of sex chromosomes (called X &Y). A female usually has XX chromosomes whereas a male has XY chromosomes.
These sex chromosomes determine the gender of a person, the height as well as development of sexual organs.
During mitosis only one X chromosome transfers to the egg for a female baby.
DiagnosisAmniocentesis the prenatal diagnosis of chromosomal
abnormalities during pregnancy.Chromosome analysis.Finding the specific chromosome problem of the syndrome is
the only definitive diagnosis. Learning problems that lead to difficulty with math and spatial
relationships between objects.Blood Hormone levels Echocardiogram (heart ultrasound) MRI of ChestUltrasound of reproductive organs and kidneys Pelvic Exam
