Liddle Syndrome
Familial pseudoaldosteronism characterized by autosomal dominant inheritance of hypertension with HYPOKALEMIA; ALKALOSIS; RENIN and ALDOSTERONE level decreases. It is caused by mutations in EPITHELIAL SODIUM CHANNELS beta and gamma subunits. Different mutations in the same EPITHELIAL SODIUM CHANNELS subunits can cause PSEUDOHYPOALDOSTERONISM, TYPE I, AUTOSOMAL DOMINANT.

BACKGROUND: Liddle's syndrome is a rare autosomal-dominant monogenic form of salt-sensitive hypertension. This study aimed to screen the gene mutation in beta and gamma subunits of the epithelial sodium channel (ENaC) of a Chinese family with Liddle's syndrome, an autosomal dominant form of hypertension. METHODS: DNA samples from the proband with early-onset, treatment-resistant hypertension and suppressed plasma renin activity were initially screened for mutations in the C-terminal exons of the ENaC beta or gamma subunit genes, using amplification by polymerase chain reaction and direct DNA sequencing. We also screened the C-terminus of SCNN1B and SCNN1G in family members, and screened for the mutation in 150 controls. RESULTS: Genetic analysis of the beta ENaC gene revealed a missense mutation of CCC to TCC at codon 616 in the proband, her mother and her grandmother. One hundred and fifty randomly selected controls had not the mutation, indicating that this is not a common genetic polymorphism. There was no mutation of the gamma ENaC gene in any of the individuals examined. CONCLUSIONS: Through direct DNA sequencing analysis, we established the diagnosis of Liddle's syndrome for the proband and her families, and provided tailored therapies to this abnormality. These results provide further evidence that Pro616Ser is a critical amino acid that has a key role in the inhibition of sodium channel activity.

(+info)Liddle Syndrome is a rare, inherited form of low-renin hypertension characterized by early onset of severe high blood pressure, hypokalemia, and metabolic alkalosis due to mutations in the epithelial sodium channel (ENaC), leading to increased sodium reabsorption in the distal tubules of the kidney.
Liddle Syndrome is a rare genetic disorder that affects the kidney's ability to regulate sodium and potassium levels in the body. It is characterized by early onset hypertension (high blood pressure), hypokalemia (low potassium levels), and metabolic alkalosis (a shift in the body's acid-base balance towards higher pH).
The disorder is caused by mutations in the SCNN1B and SCNN1G genes, which encode for subunits of the epithelial sodium channel (ENaC) in the distal tubules of the kidney. These mutations lead to an overactive ENaC, resulting in increased sodium reabsorption and potassium excretion, which ultimately causes hypertension and hypokalemia.
Liddle Syndrome is typically inherited in an autosomal dominant manner, meaning that only one copy of the mutated gene is sufficient to cause the disorder. Treatment usually involves the use of medications that block the ENaC channel, such as amiloride or triamterene, which can help control blood pressure and correct electrolyte imbalances.
'Epithelial Sodium Channels' are transmembrane protein complexes, primarily expressed in epithelial cells, responsible for the regulation of sodium transport and fluid homeostasis, which play a crucial role in various physiological processes including blood pressure control and maintenance of body fluid balance.
Epithelial Sodium Channels (ENaC) are a type of ion channel found in the epithelial cells that line the surface of many types of tissues, including the airways, kidneys, and colon. These channels play a crucial role in regulating sodium and fluid balance in the body by allowing the passive movement of sodium ions (Na+) from the lumen or outside of the cell to the inside of the cell, following their electrochemical gradient.
ENaC is composed of three subunits, alpha, beta, and gamma, which are encoded by different genes. The channel is normally closed and opens in response to various stimuli, such as hormones, neurotransmitters, or changes in osmolarity. Once open, the channel allows sodium ions to flow through, creating a positive charge that can attract chloride ions (Cl-) and water molecules, leading to fluid absorption.
In the kidneys, ENaC plays an essential role in regulating sodium reabsorption in the distal nephron, which helps maintain blood pressure and volume. In the airways, ENaC is involved in controlling the hydration of the airway surface liquid, which is necessary for normal mucociliary clearance. Dysregulation of ENaC has been implicated in several diseases, including hypertension, cystic fibrosis, and chronic obstructive pulmonary disease (COPD).
A syndrome is a set of symptoms that collectively indicate a specific disease, disorder, or condition, often representing a common pathway or pattern of underlying physiological processes and/or anatomical abnormalities.
A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.
For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.
It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.
'Sodium channels' are transmembrane protein complexes that facilitate the selective flow of sodium ions (Na+) through the cell membrane, crucial for generating and propagating action potentials in excitable cells such as neurons and muscle fibers.
Sodium channels are specialized protein structures that are embedded in the membranes of excitable cells, such as nerve and muscle cells. They play a crucial role in the generation and transmission of electrical signals in these cells. Sodium channels are responsible for the rapid influx of sodium ions into the cell during the initial phase of an action potential, which is the electrical signal that travels along the membrane of a neuron or muscle fiber. This sudden influx of sodium ions causes the membrane potential to rapidly reverse, leading to the depolarization of the cell. After the action potential, the sodium channels close and become inactivated, preventing further entry of sodium ions and helping to restore the resting membrane potential.
Sodium channels are composed of a large alpha subunit and one or two smaller beta subunits. The alpha subunit forms the ion-conducting pore, while the beta subunits play a role in modulating the function and stability of the channel. Mutations in sodium channel genes have been associated with various inherited diseases, including certain forms of epilepsy, cardiac arrhythmias, and muscle disorders.
Hypertension is a chronic medical condition characterized by consistently elevated systolic and/or diastolic blood pressure levels, which can lead to severe complications such as heart disease, stroke, and kidney failure if left untreated or uncontrolled.
Hypertension is a medical term used to describe abnormally high blood pressure in the arteries, often defined as consistently having systolic blood pressure (the top number in a blood pressure reading) over 130 mmHg and/or diastolic blood pressure (the bottom number) over 80 mmHg. It is also commonly referred to as high blood pressure.
Hypertension can be classified into two types: primary or essential hypertension, which has no identifiable cause and accounts for about 95% of cases, and secondary hypertension, which is caused by underlying medical conditions such as kidney disease, hormonal disorders, or use of certain medications.
If left untreated, hypertension can lead to serious health complications such as heart attack, stroke, heart failure, and chronic kidney disease. Therefore, it is important for individuals with hypertension to manage their condition through lifestyle modifications (such as healthy diet, regular exercise, stress management) and medication if necessary, under the guidance of a healthcare professional.

Aldosterone4
- spironolactone is not effective because it acts by regulating aldosterone and Liddle syndrome does not respond to this regulation. (wikipedia.org)
- PURPOSE: Through describing the confusing misdiagnosis process of Liddle syndrome, we try to reveal the importance of accurate aldosterone-renin detection and a genetic test for Liddle syndrome. (bvsalud.org)
- Conn's syndrome is overproduction of the mineralocorticoid hormone aldosterone by the adrenal glands. (the-medical-dictionary.com)

- The latter group includes Liddle syndrome, a rare genetic disease with autosomal dominant inheritance, caused by gain-of-function mutations in the genes that code for the epithelial sodium channel (ENaC), involved in sodium reabsorption in the distal renal tubules. (bvsalud.org)
- In Liddle syndrome, ENaC activity get at least 30 minutes to exercise physical activity. (rsmraiganj.in)
- Some people with the Liddle phenotype have Liddle syndrome, which involves a genetic mutation resulting in upregulation of the epithelial sodium channel (ENaC), located in the apical membrane of polarized epithelial cells in the late distal tubule and collecting duct of the kidney. (worldsbest.rehab)
