Health Conditions Related to Genetic Changes
Genetic changes in the MUTYH gene can result in various health conditions. The MUTYH gene provides instructions for making a protein called DNA glycosylase, which plays a critical role in DNA replication and repair.
Changes in the MUTYH gene can lead to a variant form of MUTYH-associated polyposis (MAP), a condition characterized by the development of multiple adenomatous polyps in the colon and rectum. If left untreated, these polyps can become cancerous.
Mutations in the MUTYH gene can also cause an autosomal recessive condition known as MUTYH-associated polyposis, which is similar to classic familial adenomatous polyposis (FAP). This condition is characterized by the presence of multiple adenomatous polyps in the colon and rectum, increasing the risk of colorectal cancer.
This article provides information on health conditions related to genetic changes in the MUTYH gene. The details of the changes, their position in the gene, and the associated diseases are described. The information is compiled from scientific articles, databases, and resources such as OMIM, PubMed, and the MUTYH gene mutation database.
If you are interested in testing for MUTYH gene mutations or need additional information on related health conditions, you can refer to the MUTYH Gene Mutation Database, OMIM, or consult with a genetics professional. They can provide you with further resources and guidance on the testing process.

Familial adenomatous polyposis
Familial adenomatous polyposis (FAP) is a genetic condition caused by mutations in the MUTYH gene. FAP is characterized by the development of numerous adenomatous polyps, mainly in the colon and rectum.
Individuals with FAP have an increased risk of developing colorectal cancer at a young age. The condition is inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to each of their children.
The MUTYH gene is involved in DNA repair, specifically in the removal of DNA damage caused by oxidative stress. The gene encodes the MUTYH glycosylase enzyme, which recognizes and excises mismatched bases formed by the misincorporation of adenine opposite oxidatively damaged cytosine in DNA during replication. Mutations in the MUTYH gene impair this repair process, leading to an accumulation of DNA damage and an increased risk of cancer development.
There are several types of mutations in the MUTYH gene that can cause FAP. The most common mutation is the c.536A>G (p.Tyr179Cys) variant, which is associated with a classic form of FAP. Other mutations include c.1187G>A (p.Gly396Asp) and c.494A>G (p.Tyr165Cys). Genetic testing can be used to identify these mutations and determine an individual’s risk of developing FAP.
In addition to FAP, mutations in the MUTYH gene can also be associated with other conditions, such as attenuated adenomatous polyposis coli (AAPC) and MUTYH-associated polyposis (MAP). AAPC is characterized by a smaller number of polyps compared to FAP, while MAP is characterized by a higher risk of colorectal cancer.
Resources for further information on FAP and MUTYH gene mutations include scientific articles, databases, and genetic testing laboratories. The Online Mendelian Inheritance in Man (OMIM) database provides detailed information on the genetic basis of FAP and related conditions. PubMed is a catalog of scientific articles, including those related to FAP and MUTYH gene mutations. The MUTYH Genetic Testing Registry is a database of genetic testing laboratories that offer tests for MUTYH gene mutations.
In conclusion, familial adenomatous polyposis is a genetic condition caused by mutations in the MUTYH gene. It is characterized by the development of numerous adenomatous polyps in the colon and rectum, and individuals with FAP have an increased risk of developing colorectal cancer. Genetic testing can be used to identify these mutations and determine an individual’s risk for FAP and related conditions.
