Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder that primarily affects males. It is named after Charles Lowe, the physician who first described the condition in 1952. Lowe syndrome is characterized by three main features: cataracts that develop in infancy, intellectual disability, and kidney problems.
The genetic cause of Lowe syndrome has been identified as mutations in the OCRL gene, which is located on the X chromosome. This gene provides instructions for making an enzyme called OCRL, which helps regulate the levels of certain phospholipids in cells. Mutations in the OCRL gene result in a shortage of functional OCRL enzyme, leading to the signs and symptoms of Lowe syndrome.
Lowe syndrome has been assigned the OMIM number 309000 by the Online Mendelian Inheritance in Man (OMIM) database, which provides comprehensive information about genetic diseases. The frequency of Lowe syndrome is estimated to be approximately 1 in 500,000 individuals worldwide.
In addition to genetic testing for the OCRL gene, there are other resources available for individuals and families affected by Lowe syndrome. The Lowe Syndrome Association is an advocacy and support organization that provides information, resources, and support to individuals with Lowe syndrome and their families. ClinicalTrials.gov is a database of clinical studies that are currently being conducted, which may provide additional opportunities for research and treatment options for individuals with Lowe syndrome.
More information about Lowe syndrome can be found in scientific articles, research studies, and clinical trial publications. PubMed and the Catalog of Human Genes and Genetic Disorders are databases that contain references to articles and studies about Lowe syndrome and other related conditions. These resources can provide valuable information for individuals and families seeking to learn more about the causes, symptoms, and management of Lowe syndrome.
Frequency
Lowe syndrome is a rare genetic condition that primarily affects males. The frequency of Lowe syndrome is estimated to be between 1 in 500,000 and 1 in 1,000,000 individuals worldwide. The exact number of affected individuals is unknown, as this syndrome is often misdiagnosed or undiagnosed.
Part of the reason for these long wait times and short appointments is due to a nationwide shortage of physicians that is only getting worse. A report by the Association of American Medical Colleges predicts that, due to population growth and specifically growth of the elderly population, the physician shortfall in the U.S. could reach 121,300 by the year 2030.

Causes
The main cause of Lowe syndrome is mutations in the OCRL gene, which provides instructions for producing the protein called OCRL. This gene is located on the X chromosome.
Lowe syndrome is inherited in an X-linked recessive pattern, which means that the condition primarily affects males. Females can also be affected, but it is generally less severe due to the presence of a second, normal copy of the gene.
The OCRL protein is involved in the regulation of phospholipids, which are important components of cell membranes. Mutations in the OCRL gene result in a shortage or malfunctioning of the OCRL protein, which disrupts various cellular processes.
Further information about the OCRL gene and Lowe syndrome can be found on the Online Mendelian Inheritance in Man (OMIM) database and the National Center for Biotechnology Information’s gene database (Gene). These resources provide detailed genetic and clinical information about the condition, as well as references to scientific articles and other research studies.
Genetic testing for Lowe syndrome can confirm the diagnosis by identifying mutations in the OCRL gene. Testing can be done through specialized laboratories and genetic testing centers. It is recommended to seek advice from genetic counselors and healthcare professionals to learn more about the available testing options and their associated benefits and limitations.
It is important to note that Lowe syndrome is a rare condition, and genetic testing is not the only way to diagnose it. The diagnosis is typically based on the presence of characteristic symptoms and clinical features, such as oculocerebrorenal syndrome and vision problems. Additional tests, such as urinary amino acid analysis and biochemical assays, may also be performed to support the diagnosis.
Research studies and clinical trials (registered on ClinicalTrials.gov) are ongoing to further understand the causes of Lowe syndrome, develop potential treatments, and improve patient care. These resources can provide information about ongoing studies, available treatments, and opportunities to participate in clinical trials.
