What is the difference between a monogenic disorder and a chromosomal disorder?

Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example. Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes.

What is monogenic disorder?

Monogenic disorders (monogenic traits) are disorders caused by variation in a single gene and are typically recognized by their striking familial inheritance patterns. Examples include sickle cell anemia, cystic fibrosis, Huntington disease, and Duchenne muscular dystrophy.

What is a chromosomal disorder?

Chromosomal disorder, any syndrome characterized by malformations or malfunctions in any of the body's systems, and caused by abnormal chromosome number or constitution.

What is the difference between a chromosomal and gene mutation?

Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.

What diseases are caused by chromosomal abnormalities?

Examples of chromosomal abnormalities include Down syndrome, Trisomy 18, Trisomy 13, Klinefelter syndrome, XYY syndrome, Turner syndrome and triple X syndrome.

What are 3 types of chromosomal mutations?

The three major single-chromosome mutations: deletion (1), duplication (2) and inversion (3). The two major two-chromosome mutations: insertion (1) and translocation (2).

What is the most common monogenic disorder?

The best-known monogenic respiratory diseases are CF and α1-antitrypsin deficiency, but hundreds of rare monogenic diseases affecting the respiratory system have been described.

What is a Mendelian disorder?

In humans, Mendelian disorder is a type of genetic disorder primarily resulting due to alterations in one gene or as a result of abnormalities in the genome. Such a condition can be seen since birth and be deduced on the basis of family history using the family tree. ... Genetic disorders may or may not be inherited.

What is the cause of monogenic disease?

These disorders are the result of a single defective gene on the autosomes. They are inherited according to Mendel's Laws (Mendelian disorders). The mutation can be spontaneous and where there is no previous family history.

What is the most common chromosomal disorder?

The most common type of chromosomal abnormality is known as aneuploidy, an abnormal chromosome number due to an extra or missing chromosome. Most people with aneuploidy have trisomy (three copies of a chromosome) instead of monosomy (single copy of a chromosome).

What are the two reasons for chromosomal disorders?

Chromosome abnormalities often happen due to one or more of these: Errors during dividing of sex cells (meiosis) Errors during dividing of other cells (mitosis) Exposure to substances that cause birth defects (teratogens)

Can you fix chromosomal abnormalities?

In many cases, there is no treatment or cure for chromosomal abnormalities. However, genetic counseling, occupational therapy, physical therapy and medicines may be recommended.
