What is the genotype of someone with Turner’s syndrome?

What is the genotype of Turner’s syndrome?

This type of chromosomal abnormality is also known as the monosomy of the X chromosome and the genotype of such females is represented as 44A+XO, where A represents the Autosomes.

What is the genotype of a female with Turner syndrome?

Turner syndrome is diagnosed in females based on clinical presentation combined with a genotype consisting of one normal X chromosome and complete or partial absence of the other X chromosome [1.

What chromosomes does a person have if they have Turner syndrome?

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

What does monosomy mean?

The term “monosomy” is used to describe the absence of one member of a pair of chromosomes. Therefore, there are 45 chromosomes in each cell of the body instead of the usual 46.

Is Turner syndrome dominant or recessive?

Turner syndrome only occurs in females. Noonan syndrome, sometimes inappropriately called male Turner syndrome, can occur in males or females. It is an autosomal dominant genetic disorder and is not a chromosomal disorder.

Can you live with monosomy 21?

Monosomy 21 is a very rare condition with less than 50 cases described in the literature. Full monosomy 21 is probably not compatible with life.
