Alström syndrome is a rare genetic condition that affects multiple organs and potentially causes a range of medical problems. This article provides an overview of Alström syndrome, including information about its causes, inheritance pattern, associated symptoms, and available resources for support and research.

First described in the medical literature in 1959 by Carl-Henry Alström, this syndrome is caused by mutations in the ALMS1 gene. The ALMS1 gene provides instructions for making a protein that is involved in the structure and function of cilia, which are microscopic, finger-like projections found on the surface of many cells throughout the body. These cilia play important roles in various cellular processes, and dysfunction of cilia can lead to the development of Alström syndrome.

Alström syndrome is inherited in an autosomal recessive pattern, which means that both copies of the ALMS1 gene must have mutations for the syndrome to be present. The frequency of Alström syndrome is extremely rare, estimated to affect approximately 1 in every 1 million individuals worldwide.

Individuals with Alström syndrome may experience a wide range of medical problems, including obesity, diabetes, increased sensitivity to light (photophobia), hearing loss, and kidney, liver, and heart disease. Other symptoms may include vision problems, hormonal abnormalities, and developmental delays. The severity and specific combination of symptoms can vary greatly among affected individuals.

For families and individuals living with Alström syndrome, there are several resources available for support and information. Organizations like the Alström Syndrome UK and Alström Syndrome International provide advocacy, resources, and publications about the condition. Additionally, the Alström Syndrome Disease Support Center offers genetic testing, clinical trials information, and additional resources for patient families.

Frequency

Alström syndrome is a rare genetic disorder that is estimated to occur in fewer than 1 in 100,000 individuals worldwide. It has been reported in various populations across the world.

Denied health insurance claims are a major problem for patients in America. The Kaiser Family Foundation found that ACA marketplace plans denied about 17% of in-network claims in 2019.

Alström syndrome is caused by mutations in the ALMS1 gene, which is located on chromosome 2. Mutations in this gene are responsible for the characteristic features and symptoms of the condition. ALMS1 gene mutations are inherited in an autosomal recessive pattern, which means that an individual must inherit two copies of the mutated gene – one from each parent – to develop the syndrome.

The rarity of Alström syndrome and the wide range of symptoms associated with the condition can make it difficult to diagnose. Genetic testing is available to confirm a suspected diagnosis of Alström syndrome. This testing can identify mutations in the ALMS1 gene and is usually performed when a person presents with clinical features consistent with the syndrome. It is important to note that not all individuals with Alström syndrome will have a mutation in the ALMS1 gene, and alternative genetic testing may be necessary to identify the underlying cause in these cases.

Research studies have identified other genes and genetic factors that may be associated with a similar spectrum of symptoms seen in Alström syndrome. These include genes such as BBS1, BBS2, BBS3, and BBS4, which are associated with Bardet-Biedl syndrome. Alström syndrome and Bardet-Biedl syndrome are considered to be part of a broader group of overlapping genetic disorders known as ciliopathies.

Additional information about the frequency and inheritance of Alström syndrome can be found in the OMIM (Online Mendelian Inheritance in Man) database, which catalogues genetic disorders and provides detailed information about their clinical features, genetic causes, and inheritance patterns. Scientific articles published in PubMed can also provide more information on the frequency and genetic causes of Alström syndrome.

For additional support and information about Alström syndrome, patients and their families can contact the Alström Syndrome International Support Center or consult resources from other organizations such as the National Organization for Rare Disorders (NORD). Clinical trials may also be available for individuals with Alström syndrome, and information about ongoing trials can be found on ClinicalTrials.gov.

Causes

Alström syndrome is a rare genetic condition that affects multiple organ systems in the body. It is caused by mutations in the ALMS1 gene. The ALMS1 gene provides instructions for making a protein that is involved in the development and function of various tissues and organs.

According to scientific research, there are more than 200 different mutations in the ALMS1 gene that can cause Alström syndrome. These mutations can disrupt the normal functioning of the protein and lead to the signs and symptoms of the condition.

Alström syndrome is inherited in an autosomal recessive pattern, which means that both copies of the ALMS1 gene must have mutations in order for the condition to develop. If a person has only one mutated copy of the gene, they are considered to be a carrier of Alström syndrome but do not typically show any symptoms of the condition.

To learn more about the causes of Alström syndrome, you can visit various resources such as the National Institutes of Health’s Genetic and Rare Diseases Information Center, the Online Mendelian Inheritance in Man (OMIM) catalog, and PubMed, which is a database of scientific articles. These resources provide additional information about the research and genetic testing associated with Alström syndrome.

ClinicalTrials.gov is another valuable resource that provides information about ongoing clinical trials for Alström syndrome. These trials may investigate new treatments, explore the natural history of the condition, or collect data to better understand the causes and progression of the disease.

In addition to these resources, there are several patient advocacy and support organizations that provide information and support for individuals and families affected by Alström syndrome. These organizations can help connect individuals with healthcare providers, provide educational materials, and offer support for managing the condition.
