Proteins which are found in membranes including cellular and intracellular membranes. They consist of two types, peripheral and integral proteins. They include most membrane-associated enzymes, antigenic proteins, transport proteins, and drug, hormone, and lectin receptors.

The hallmark symptom of RA is an inability to reabsorb these amino acids, leading to their excessive excretion in the urine. This can cause a range of health problems, including:

1. Cystinuria: excessive excretion of cystine in the urine, which can form stones and damage the kidneys.
2. Glutaric aciduria type 1 (GA1): excessive excretion of glutaric acid and other branched-chain amino acids in the urine, which can lead to developmental delays, intellectual disability, and seizures.
3. Aminoaciduria: excessive excretion of various amino acids in the urine, including alanine, glycine, and proline.
4. Kidney damage: chronic exposure to high levels of certain amino acids in the urine can cause damage to the kidneys, leading to chronic kidney disease and potentially end-stage renal disease (ESRD).
5. Other complications: RA can also lead to other health problems, such as electrolyte imbalances, bone disease, and metabolic acidosis.

RA is diagnosed through a combination of clinical evaluation, laboratory tests, and genetic analysis. Treatment typically involves a combination of dietary restrictions, medications, and kidney transplantation in severe cases.

Cystinuria is caused by mutations in the SLC7A9 gene, which codes for a protein involved in the transport of cystine across the brush border membrane of renal tubular cells. The disorder is inherited in an autosomal recessive pattern, meaning that affected individuals must inherit two copies of the mutated gene (one from each parent) to develop symptoms.

There is no cure for cystinuria, but various treatments can help manage its symptoms. These may include medications to reduce the acidity of the urine and prevent infection, as well as surgical procedures to remove stones or repair damaged kidneys. In some cases, a kidney transplant may be necessary.

It's important for individuals with cystinuria to drink plenty of water and maintain good hydration to help flush out the urinary tract and prevent stone formation. They should also avoid certain foods that may increase the risk of stone formation, such as oxalate-rich foods like spinach and rhubarb.

Overall, while there is no cure for cystinuria, with proper management and care, individuals with this disorder can lead relatively normal lives and minimize the complications associated with it.

  • The transcriptome data revealed that the gene repertoire related to defenses, nutrient transport, and carbohydrates differs between nonmycorrhizal and mycorrhizal plants with aphids, which could explain the weight gain in aphids. (bvsalud.org)
