Glucose-galactose malabsorption is a congenital genetic condition associated with the inability to absorb glucose and galactose, two types of sugars, in the small intestinal tract. This rare disorder affects the transport proteins responsible for moving glucose and galactose into the cells of the small intestine.

Patients with glucose-galactose malabsorption have severe diarrhea, glucosuria (glucose in the urine), and failure to thrive. The main treatment for this condition is maintaining a strict diet that eliminates all sources of glucose and galactose.

Research on glucose-galactose malabsorption is ongoing, and studies have identified several genes associated with this condition. The OMIM database provides more information on the genetic basis and inheritance patterns of glucose-galactose malabsorption. Additional scientific articles can be found on PubMed and other research resources.

The advocacy and support center for glucose-galactose malabsorption offers resources and information for patients and their families. Clinical trials for new treatments and management strategies can be found on ClinicalTrials.gov. It is important for patients and healthcare providers to stay informed about the latest research and advances in the understanding of this condition.

Frequency

Glucose-galactose malabsorption is a rare genetic condition with a frequency of approximately 1 in 50,000 to 100,000 live births. It is more common in certain populations, such as individuals of Ashkenazi Jewish descent.

The gene associated with glucose-galactose malabsorption is SLC5A1, located on chromosome 22. Mutations in this gene result in a deficiency of the SGLT1 protein, which is responsible for absorbing glucose and galactose from the small intestine into the bloodstream.

As it is, health care taxes are higher in the United States than in any other country in the world – even those with universal healthcare programs, according to Physicians for a National Health Program. The full amount of health care taxes American taxpayers cover includes government programs such as Medicare, Medicaid and the Veterans Administration as well as tax subsidies and the cost of private health insurance for public employees.

Studies have shown that there are more than 55 different mutations in the SLC5A1 gene that can cause glucose-galactose malabsorption. These mutations can vary in their severity and can lead to a complete absence or reduced function of the SGLT1 protein.

The symptoms of glucose-galactose malabsorption usually appear within a few days after birth and can include severe diarrhea, vomiting, and dehydration. If left untreated, this condition can be life-threatening.

Diagnosis of glucose-galactose malabsorption can be confirmed through genetic testing or through a glucose-galactose breath test. Other tests, such as blood and urine tests, may also be performed to evaluate the function of the SGLT1 protein.

Treatment for glucose-galactose malabsorption involves completely eliminating glucose and galactose from the diet. This means avoiding foods that contain lactose, such as milk and dairy products, as well as foods that contain added sugars, such as candies and sweetened beverages. Patients with glucose-galactose malabsorption require a strict diet that consists of foods that do not contain glucose or galactose, such as certain fruits, vegetables, and proteins.

Patient support and advocacy groups, such as the Glucose-Galactose Malabsorption Support Group, provide valuable resources and information for individuals and families affected by this condition. These groups can provide education, support, and opportunities for individuals to connect with others who are facing similar challenges.

Research into glucose-galactose malabsorption is ongoing, and there are many scientific articles and studies available on the topic. Additional information can be found on websites such as PubMed, OMIM, and ClinicalTrials.gov, which catalog references, articles, and clinical trials related to this condition.

Causes

The causes of glucose-galactose malabsorption (GGM) are primarily associated with genetic factors and diet.

This rare condition is commonly inherited in an autosomal recessive pattern, meaning that both parents must pass on a copy of the mutated gene for a child to develop GGM. There are several genes that have been associated with GGM, including SGLT1 (SLC5A1) and SGLT2 (SLC5A2).

Individuals with GGM have a mutation in the SGLT1 gene, which affects the function of the sodium-dependent glucose transporter 1 protein. This protein is responsible for the absorption of glucose and galactose in the small intestine.

The main symptom of GGM is the inability to absorb glucose and galactose, leading to severe diarrhea and dehydration. Rare signs and symptoms can also include glucosuria (glucose in the urine) and failure to thrive, especially in infants.

While there is no cure for GGM, the condition can be managed through dietary changes. Individuals with GGM must follow a strict diet that eliminates all sources of glucose and galactose, including dairy products, fruits, and certain grains. Instead, they must rely on alternative sources of carbohydrates for their nutritional needs.

Research on GGM is ongoing, and several clinical trials are currently underway to investigate potential treatments and interventions. A variety of resources, including scientific articles, patient advocacy groups, and genetic testing centers, provide more information on GGM and can support individuals and their families in managing the condition.

Learn more about the gene associated with Glucose-galactose malabsorption

Glucose-galactose malabsorption is a rare condition characterized by the inability to absorb glucose and galactose in the gastrointestinal tract. It is caused by mutations in the SLC5A1 gene, which encodes the glucose-galactose transporter protein.

Glucose-galactose malabsorption is inherited in an autosomal recessive pattern, meaning that both copies of the SLC5A1 gene must have mutations for the condition to occur. The mutations in the SLC5A1 gene result in a malfunctioning glucose-galactose transporter protein, which prevents the absorption of glucose and galactose from the diet into the cells of the small intestine.

Patients with glucose-galactose malabsorption typically experience signs and symptoms such as severe diarrhea, dehydration, and failure to thrive. These symptoms usually appear shortly after birth when the affected infant begins feeding with formula or breast milk containing glucose and galactose.

Genetic testing can be used to confirm a diagnosis of glucose-galactose malabsorption. Testing can identify mutations in the SLC5A1 gene that are associated with the condition. More information on genetic testing for glucose-galactose malabsorption can be found at the OMIM website.

There is currently no cure for glucose-galactose malabsorption, but the condition can be managed through a strict diet that eliminates sources of glucose and galactose. This usually involves feeding the affected individual with a specialized formula that does not contain glucose and galactose.

Inheritance

Glucose-galactose malabsorption (GGM) is a rare genetic condition that causes an intolerance of glucose and galactose. It is inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the mutated gene for it to be passed on to their child. The condition is caused by mutations in the SLC5A1 gene, which is involved in the absorption of glucose and galactose in the small intestine.

Individuals with glucose-galactose malabsorption are unable to properly absorb these sugars from their diet, leading to a range of symptoms. Common signs and symptoms of GGM include severe diarrhea, dehydration, failure to thrive, and glucosuria (the presence of glucose in the urine). These symptoms typically begin shortly after birth, when the baby is first fed with a diet containing glucose or galactose.

More information about the causes, symptoms, and genetic inheritance of glucose-galactose malabsorption can be found in scientific articles and research resources. The Online Mendelian Inheritance in Man (OMIM) database and PubMed are valuable resources for learning more about this condition and the associated genetic mutations.

Genetic testing is available to confirm a diagnosis of glucose-galactose malabsorption. This testing can identify mutations in the SLC5A1 gene that are associated with the condition. It is important for individuals with GGM and their families to receive genetic counseling and support to better understand the inheritance pattern and manage the condition.

The frequency of glucose-galactose malabsorption in the general population is unknown, but it is considered to be a rare disease. Advocacy groups and patient support organizations can provide additional information and resources for individuals and families affected by GGM.
