What is chromosome 23 disorder?
In females, the 23 rd pair is two X chromosomes. In males, the 23rd pair is one X and one Y chromosome. There are 2 types of Turner syndrome: monosomy X TS and mosaic TS. About half of all girls with Turner syndrome have a monosomy disorder. Monosomy means that a person is missing one chromosome in the pair.
What chromosomes cause genetic disorders?
 Other common types of numerical disorders include trisomy 13, trisomy 18, Klinefelter syndrome and Turner syndrome. Chromosomal deletions, sometimes known as partial monosomies, occur when a piece or section of chromosomal material is missing. Deletions can occur in any part of any chromosome.
What is the life expectancy of a person 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.

According to research, Klinefelter syndrome can shorten your life expectancy up to two years. However, you can still live a long, full life with this condition. The earlier you get treatment, the better your outlook will be.
What causes a genetic disorder?
Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that …
What is chromosomal genetic disorder?

What diseases are caused by chromosomal mutations?
But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others. All of these disorders are caused by the mutation of a single gene.
What are the different types of chromosomal disorders?

What are rare chromosome disorders?
Rare chromosome disorders include extra, missing or re-arranged chromosome material but do not include the more common chromosome conditions such as Down’s Syndrome. Using the latest technology, it is now possible for smaller and more complex chromosome defects to be identified.
What are abnormal chromosomes?
Chromosomal Abnormalities (Overview) A chromosome anomaly, abnormality, aberration, or mutation is a missing, extra, or irregular portion of chromosomal DNA. It can be from an atypical number of chromosomes or a structural abnormality in one or more chromosomes.
