Fanconi Syndrome

Fanconi Syndrome is a disease affecting the proximal convoluted tubules of the nephrons; may be hereditary or acquired, and is more common in children. Its main symptom is the excretion of urine containing large amounts of various amino acids, glucose and phosphates (despite the fact that the content of these substances in the blood remains normal). Patients may also experience osteomalacia, rickets, muscle weakness and cystinosis. Treatment is aimed at eliminating the cause of the disease.



Fanconi Syndrome is a rare disease that affects the proximal convoluted tubules of the nephrons, which are responsible for the reabsorption of substances needed by the body. This disease can be either hereditary or acquired, and most often occurs in children.

One of the main symptoms of Fanconi syndrome is the production of urine containing large amounts of various amino acids, glucose and phosphates. Despite this, the content of these substances in the blood remains within normal limits. This phenomenon is called glycosuria, amino aciduria and phosphaturia.

Patients with Fanconi syndrome may also develop other symptoms such as osteomalacia (sprained bones), rickets (deformed bones), muscle weakness, and cystinosis (accumulation of cystine in tissues).

The causes of Fanconi syndrome can be varied, including inherited mutations, infections, toxic exposures and other diseases. Treatment of this disease is aimed at eliminating the cause of the syndrome and may include the use of various medications and diet.

The hereditary form of Fanconi syndrome is rare, but can be inherited in either a dominant or recessive manner. In this case, the genes responsible for the syndrome may be associated with various proteins, including proteins involved in the transport of substances through the proximal convoluted tubule.

The acquired form of Fanconi syndrome can be caused by various causes, such as infections, toxins, drugs, or other diseases such as myeloma or Wilson-Konovalov disease.

In general, Fanconi syndrome is a rare and complex disease that requires long-term and complex treatment. However, with timely seeking help and proper treatment, most patients with Fanconi syndrome can achieve improvement in their condition and a better quality of life.



Fanconi syndrome is a group of inherited diseases that affect the proximal tubules of the kidneys. It can be either hereditary or acquired. Fanconi syndrome most often occurs in children and is characterized by the production of urine containing various amino acids, glucose and phosphates. This occurs despite the fact that the levels of these substances in the blood remain normal.

Patients with Fanconi syndrome may also exhibit symptoms such as osteomalacia (a bone disease), rickets (a disorder of skeletal development), muscle weakness, and cystinosis (a disorder of cystine metabolism).

Treatment of Fanconi syndrome is aimed at eliminating the causes of the disease. In some cases, a kidney or other organ transplant may be required. In addition, patients may receive drug therapy to improve and maintain health.

Fanconi syndrome is a serious disease that requires timely diagnosis and treatment. Patients with this syndrome require constant monitoring and care to prevent possible complications and improve their quality of life.
