Can males be carriers of Turner syndrome?
Noonan syndrome affects both males and females, and there is a normal chromosomal makeup (karyotype). Only females are affected by Turner syndrome, which is characterized by abnormalities affecting the X chromosome.
Why can’t males have Turner syndrome?
Turner syndrome is caused by a female having one normal X chromosome in each of her cells , while the other sex chromosome is either missing or structurally abnormal. Females without Turner syndrome have 2 full X chromosome in all of their cells, and males have one X chromosome and one Y chromosome .
Why can a male child not inherit Turner’s syndrome from their father?
Most cases of Turner syndrome are not inherited . Most commonly, Turner syndrome occurs due to a random event during the formation of an egg or sperm cell in a parent (prior to conception).
How is Turner syndrome passed down?
Most cases of Turner syndrome are not inherited. When this condition results from monosomy X , the chromosomal abnormality occurs as a random event during the formation of reproductive cells (eggs and sperm) in the affected person’s parent.
What is the lifespan of someone with Turner syndrome?
What is the long-term outlook for people with Turner syndrome? The long-term outlook ( prognosis ) for people with Turner syndrome is typically good.

Can a female have Turner’s syndrome and a male have it?
Turner syndrome happens when a female is missing certain genes that are normally on the X chromosome. (Females have two X chromosomes. Males have an X and a Y). But about 1% of the time, these babies are born, and they have the syndrome.
How is Turner syndrome inherited from a parent?
In rare cases, Turner syndrome may be caused by a missing piece (partial deletion) of the X chromosome. A deletion can be inherited from a parent. [1] Genetic testing of an affected fetus or child can identify the type of Turner syndrome present and may help to estimate the risk of recurrence.
When does mosaic Turner syndrome occur in a fetus?
Mosaic Turner syndrome, occurring when a person has some cells with one X chromosome and some cells with two X chromosomes, is also not inherited. This also occurs due to a random event, during early fetal development rather than before conception.
