The POMC gene, also known as the proopiomelanocortin gene, is responsible for producing a protein called proopiomelanocortin (POMC). This protein is a precursor that is cleaved into various smaller peptides, including adrenocorticotropic hormone (ACTH) and beta-endorphin. These peptides play crucial roles in regulating various functions in the body, including controlling pigmentation in the skin and regulating the immune response.
Changes or variants in the POMC gene can lead to different conditions and diseases related to the functioning of the peptides it produces. Disorders associated with POMC gene deficiency include ACTH deficiency and obesity, as well as other conditions that affect the brain, skin, and other organs.
Scientific articles, genetic testing information, and additional resources related to the POMC gene can be found in various databases and catalogs. OMIM (Online Mendelian Inheritance in Man) is a comprehensive online catalog that provides information on genes, diseases, and genetic variants. PubMed is a valuable resource for accessing scientific publications and research papers on the POMC gene and its functions.
The POMC gene is listed in the Genetic Testing Registry, a database that provides information on genetic tests and testing laboratories. This registry can be used to find labs that offer genetic testing for POMC gene variants and related conditions.
For more information on the POMC gene, its functions, and associated diseases, it is recommended to refer to reputable scientific journals and publications. References to such articles can be found in the references section of relevant scientific papers and research studies.
Health Conditions Related to Genetic Changes
Genetic changes in the POMC gene can lead to various health conditions and diseases. The POMC gene, which codes for proopiomelanocortin, is responsible for producing proteins and peptides that have important roles in the body.
One of the well-known functions of the POMC gene is the regulation of pigment production in melanocytes, which are responsible for skin color. Genetic changes in this gene can lead to conditions such as skin pigmentation disorders.
Another important function of the POMC gene is the production of β-endorphin, a hormone that plays a role in pain regulation. Genetic changes in this gene can affect the production of β-endorphin, leading to conditions related to pain sensitivity.
The POMC gene is also involved in the control of the adrenal glands, which produce hormones such as adrenocorticotropic hormone (ACTH). Genetic changes in this gene can result in conditions like adrenocorticotropic hormone deficiency.
Additional diseases related to genetic changes in the POMC gene include brain disorders and other health conditions. For more information on these diseases and genetic changes, references and resources such as OMIM, PubMed, and genetic testing databases can provide valuable information.

Proopiomelanocortin deficiency
Proopiomelanocortin deficiency is a genetic condition that affects the production of proopiomelanocortin (POMC) protein in humans. POMC is a preproprotein that is processed to produce various hormones and peptides that have important functions in the body.
POMC is primarily produced in the brain and skin melanocytes, where it plays a crucial role in regulating pigmentation. The protein is also produced in other cell types and has various functions, including controlling appetite, regulating immune responses, and modulating stress responses.
Deficiency in POMC production can lead to a range of conditions and symptoms. In the brain, it can result in changes in appetite regulation and the development of obesity. In the skin, it can cause pigment deficiency or changes in skin color. Additional symptoms may vary depending on the specific genetic variant affecting the POMC gene.
Diagnosis of proopiomelanocortin deficiency can be done through genetic testing. Genetic tests can identify changes in the POMC gene associated with the condition. These tests are typically available through specialized laboratories or genetic testing companies.
Information about POMC deficiency can be found in scientific databases and resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed. OMIM provides detailed information on genes and genetic diseases, while PubMed contains articles and research related to POMC deficiency and related conditions.
In addition to genetic testing, other tests, such as tests for specific hormones or peptides related to POMC function, may be conducted to support the diagnosis of proopiomelanocortin deficiency and assess its impact on various body functions.
For individuals with proopiomelanocortin deficiency, management and treatment are focused on addressing the specific symptoms and conditions associated with the deficiency. This may involve a multidisciplinary approach, including the involvement of specialists in areas such as endocrinology, genetics, dermatology, and nutrition.
Further research and studies are ongoing to understand the full spectrum of conditions related to proopiomelanocortin deficiency and its impact on human health. The scientific catalog of genetic diseases is constantly updated with new information and discoveries, providing valuable resources for researchers, healthcare professionals, and individuals affected by these conditions.
