Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy
Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) is a rare genetic condition characterized by small-vessel disease, subcortical infarcts, and progressive degeneration of the white matter in the brain. CARASIL mainly affects the central nervous system and can lead to various neurological symptoms and impairments.
The condition is caused by mutations in the HTRA1 gene, which provides instructions for making a protein that helps regulate the activity of other proteins. HTRA1 gene mutations can result in a dysfunctional protein, leading to the development of CARASIL.
Several variant names for CARASIL have been listed, including Maeda syndrome, Osawa–Maeda–Mizuta syndrome, and leukoencephalopathy, arteriopathy, and cysts. The condition has also been associated with age-related macular degeneration and some types of cancers.
Diagnosis of CARASIL usually involves a thorough clinical evaluation, imaging tests, and genetic testing to identify mutations in the HTRA1 gene. Genetic testing helps confirm the diagnosis and can also be useful for identifying family members at risk of developing the condition.
There is currently no specific treatment for CARASIL. Management aims to alleviate symptoms and provide supportive care to improve the quality of life for affected individuals.
Research on CARASIL and the related HTRA1 gene is ongoing, with studies investigating the underlying mechanisms and potential treatment options. Several articles and references related to CARASIL can be found in scientific databases such as PubMed and OMIM.

Age-related macular degeneration
Age-related macular degeneration (AMD) is a condition characterized by the gradual loss of central vision. It primarily affects older adults and is a leading cause of visual impairment in developed countries.
AMD is a complex disease that is influenced by both genetic and environmental factors. One of the genes associated with an increased risk of developing AMD is the HTRA1 gene. The HTRA1 gene provides instructions for making a protein that is involved in the normal growth and development of cells and tissues. Changes in this gene can lead to an increased risk of developing AMD.
Researchers have identified several variants of the HTRA1 gene that are associated with an increased risk of AMD. These variants have been found in different populations and may contribute to the development of the disease in different ways.
Studies have also shown that changes in the HTRA1 gene can be associated with other conditions, such as cerebral small-vessel disease and autosomal recessive subcortical leukoencephalopathy.
Understanding the role of the HTRA1 gene in AMD and other related conditions is still an active area of scientific research. Researchers are studying the protein produced by the HTRA1 gene to better understand its function and how changes in the gene may contribute to the development of these diseases.
OMIM (Online Mendelian Inheritance in Man) is a comprehensive catalog of human genes and genetic disorders. It provides information about the HTRA1 gene, including its alternative names, associated diseases, and references to scientific articles and other resources.
In addition to OMIM, other databases such as PubMed and gene testing resources also provide information on the HTRA1 gene and its role in different diseases, including AMD.
The identification of genetic changes in the HTRA1 gene and their association with AMD has important implications for the diagnosis and treatment of the condition. Genetic testing can help identify individuals who may be at increased risk of developing AMD and can guide the development of targeted therapies.
Further research is needed to fully understand the role of the HTRA1 gene in AMD and other related conditions. This will help in the development of better diagnostic tools and therapeutic strategies for individuals affected by these diseases.
