The protein complement of an organism coded for by its genome.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Proteins that originate from insect species belonging to the genus DROSOPHILA. The proteins from the most intensely studied species of Drosophila, DROSOPHILA MELANOGASTER, are the subject of much interest in the area of MORPHOGENESIS and development.
Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.

Ciliary motility disorders can affect any part of the body where cilia are found, but they most commonly affect the respiratory, gastrointestinal, and urogenital systems. These conditions can cause a range of symptoms, including recurring infections, chronic inflammation, and difficulty with breathing or swallowing.

Examples of ciliary motility disorders include primary ciliary dyskinesia (PCD), which is caused by defects in the structure and function of cilia, and other less common conditions such as ciliary abnormalities, which can be caused by genetic mutations or environmental factors.

Diagnosis of ciliary motility disorders typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Treatment for these conditions often focuses on managing symptoms and preventing complications, and may involve medications, breathing exercises, or other interventions. In some cases, surgery may be necessary to correct anatomical abnormalities or remove blockages in the respiratory or gastrointestinal tracts.

There are several types of kidney diseases that are classified as cystic, including:

1. Autosomal dominant polycystic kidney disease (ADPKD): This is the most common form of cystic kidney disease and is caused by a genetic mutation. It is characterized by the growth of numerous cysts in both kidneys, which can lead to kidney damage and failure.
2. Autosomal recessive polycystic kidney disease (ARPKD): This is a rare form of cystic kidney disease that is also caused by a genetic mutation. It is characterized by the growth of numerous cysts in both kidneys, as well as other organs such as the liver and pancreas.
3. Cystinosis: This is a rare genetic disorder that causes the accumulation of cystine crystals in the kidneys and other organs. It can lead to the formation of cysts and damage to the kidneys.
4. Medullary cystic kidney disease (MCKD): This is a rare genetic disorder that affects the medulla, the innermost layer of the kidney. It is characterized by the growth of cysts in the medulla, which can lead to kidney damage and failure.
5. Other rare forms of cystic kidney disease: There are several other rare forms of cystic kidney disease that can be caused by genetic mutations or other factors. These include hereditary cystic papillary necrosis, familial juvenile nephropathy, and others.

The symptoms of kidney diseases, cystic can vary depending on the specific type of disease and the severity of the condition. Common symptoms include:

* High blood pressure
* Proteinuria (excess protein in the urine)
* Hematuria (blood in the urine)
* Decreased kidney function
* Abdominal pain
* Weight loss
* Fatigue
* Swelling in the legs and ankles

If you suspect that you or your child may have a cystic kidney disease, it is important to seek medical attention as soon as possible. A healthcare provider can perform a physical examination, take a medical history, and order diagnostic tests such as urinalysis, blood tests, and imaging studies (such as ultrasound or CT scans) to determine the cause of the symptoms.

Treatment for cystic kidney disease will depend on the specific type of disease and the severity of the condition. Treatment options may include:

* Medications to control high blood pressure and proteinuria
* Medications to slow the progression of kidney damage
* Dialysis or kidney transplantation in advanced cases
* Cyst aspiration or surgical removal of cysts in some cases

It is important to note that there is no cure for cystic kidney disease, and the best treatment approach is to slow the progression of the disease and manage its symptoms. Early detection and aggressive management can help improve quality of life and delay the need for dialysis or transplantation.

In addition to medical treatment, there are some lifestyle modifications that may be helpful in managing cystic kidney disease. These include:

* Maintaining a healthy diet with low salt and protein intake
* Staying hydrated by drinking plenty of water
* Engaging in regular physical activity
* Avoiding harmful substances such as tobacco and alcohol
* Monitoring blood pressure and weight regularly

It is important to note that cystic kidney disease can be a serious condition, and it is important to work closely with a healthcare provider to manage the disease and slow its progression. With appropriate treatment and lifestyle modifications, many people with cystic kidney disease are able to lead active and fulfilling lives.

1. Vision loss or blindness
2. Developmental delays and intellectual disability
3. Speech and language difficulties
4. Poor coordination and balance
5. Skeletal abnormalities such as short stature, short arms, and curved spine
6. Kidney problems
7. Hearing loss
8. Increased risk of infections
9. Cleft palate or other facial defects
10. Delayed puberty or absent menstruation in females

The syndrome is caused by mutations in the Bardet-Biedl genes, which are responsible for the development and function of the body's sensory and motor systems. It is inherited in an autosomal recessive pattern, meaning that a child must inherit two copies of the mutated gene - one from each parent - to develop the condition.

There is currently no cure for Bardet-Biedl Syndrome, but treatment and management options are available to help manage the symptoms and improve quality of life. These may include:

1. Vision aids such as glasses or contact lenses
2. Speech and language therapy
3. Physical therapy to improve coordination and balance
4. Occupational therapy to develop daily living skills
5. Medications to manage infections, seizures, or other complications
6. Surgery to correct physical abnormalities such as cleft palate or spinal deformities
7. Hormone replacement therapy for delayed puberty or absent menstruation in females.

The prognosis for individuals with Bardet-Biedl Syndrome varies depending on the severity of the symptoms and the presence of any additional health issues. With appropriate management and support, many individuals with the condition are able to lead fulfilling lives and achieve their goals. However, the syndrome can be associated with a higher risk of certain health complications, such as kidney disease or respiratory infections, which can impact life expectancy.

There are two main types of PKD: autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD). ADPKD is the most common form of PKD and accounts for about 90% of all cases. It is caused by mutations in the PKD1 or PKD2 genes, which are inherited from one's parents. ARPKD is less common and is caused by mutations in the PKHD1 gene.

The symptoms of PKD can vary depending on the severity of the disease and the age of onset. Common symptoms include high blood pressure, back pain, kidney stones, urinary tract infections, and frequent urination. As the cysts grow, they can also cause complications such as kidney damage, anemia, and electrolyte imbalances.

PKD is typically diagnosed through a combination of imaging tests such as ultrasound, CT scans, and MRI, as well as genetic testing to identify the presence of the disease-causing mutations. There is no cure for PKD, but treatment options are available to manage the symptoms and slow the progression of the disease. These may include medications to control high blood pressure, pain management, and dialysis in advanced cases.

In conclusion, polycystic kidney disease (PKD) is a genetic disorder that affects the kidneys and can lead to chronic kidney disease and eventually kidney failure. It is important to be aware of the symptoms and risk factors for PKD, as well as to seek medical attention if they are present, in order to receive proper diagnosis and treatment.

* Cleft lip and/or palate
* Abnormal facial features such as short or deformed ears, small jaw, or widely spaced eyes
* Missing or deformed teeth
* Short or absent fingers or toes
* Congenital heart defects or other physical abnormalities

The symptoms of OFD can vary in severity and may include one or more of these features. The exact cause of OFD is not known, but it is thought to be related to genetic mutations that occur during fetal development. There is no cure for OFD, but treatment options may include surgery, dental care, and speech therapy to help manage the symptoms.

The term "orofaciodigital" refers to the oral (face and mouth) and digital (fingers and toes) aspects of the syndrome. The condition is usually diagnosed during infancy or childhood, and the prognosis can vary depending on the severity of the symptoms. With appropriate medical care and support, many individuals with OFD can lead active and fulfilling lives.

* Cerebral encephalocele: when the brain tissue protrudes through the skull.
* Meningoencephalocele: when the meninges (the protective covering of the brain and spinal cord) protrude through the skull along with the brain tissue.
* Mesenchymal encephalocele: when other tissues such as skin, muscle or bone protrude through the skull along with the brain tissue.

Symptoms of encephalocele can vary depending on the severity of the defect and can include:

* Protrusion of the brain or meninges through a opening in the skull
* Abnormal appearance of the head or face
* Delayed developmental milestones such as sitting, standing or walking
* Poor muscle tone
* Seizures
* Vision and hearing problems

Diagnosis of encephalocele is typically made through a combination of physical examination, imaging studies such as CT or MRI scans, and genetic testing. Treatment for encephalocele usually involves surgery to repair the opening in the skull and relieve any pressure on the brain. In some cases, additional surgeries may be necessary to correct other defects such as hydrocephalus (fluid accumulation in the brain).

Encephalocele is a rare condition, but it can have serious consequences if left untreated. Early detection and intervention are important for improving outcomes and reducing the risk of complications.

Note: Ciliophora infections are relatively rare in developed countries but are a significant cause of gastrointestinal illness in developing nations.

Some common types of cerebellar diseases include:

1. Cerebellar atrophy: This is a condition where the cerebellum shrinks or degenerates, leading to symptoms such as tremors, muscle weakness, and difficulty with movement.
2. Cerebellar degeneration: This is a condition where the cerebellum deteriorates over time, leading to symptoms such as loss of coordination, balance problems, and difficulties with speech and language.
3. Cerebellar tumors: These are abnormal growths that develop in the cerebellum, which can cause a variety of symptoms depending on their size and location.
4. Cerebellar stroke: This is a condition where blood flow to the cerebellum is interrupted, leading to damage to the brain tissue and symptoms such as weakness or paralysis of certain muscle groups.
5. Cerebellar vasculature disorders: These are conditions that affect the blood vessels in the cerebellum, leading to symptoms such as transient ischemic attacks (TIAs) or strokes.
6. Inflammatory diseases: These are conditions that cause inflammation in the cerebellum, leading to symptoms such as tremors, ataxia, and weakness.
7. Infections: Bacterial, viral, or fungal infections can affect the cerebellum and cause a range of symptoms.
8. Trauma: Head injuries or other forms of trauma can damage the cerebellum and lead to symptoms such as loss of coordination, balance problems, and memory loss.
9. Genetic disorders: Certain genetic mutations can affect the development and function of the cerebellum, leading to a range of symptoms.
10. Degenerative diseases: Conditions such as multiple sclerosis, Parkinson's disease, and Huntington's disease can cause degeneration of the cerebellum and lead to symptoms such as tremors, ataxia, and weakness.

It's important to note that this is not an exhaustive list, and there may be other causes of cerebellar symptoms not included here. A healthcare professional can help determine the underlying cause of your symptoms based on a thorough medical history and examination.

Some common types of eye abnormalities include:

1. Refractive errors: These are errors in the way the eye focuses light, causing blurry vision. Examples include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related loss of near vision).
2. Amblyopia: This is a condition where the brain favors one eye over the other, causing poor vision in the weaker eye.
3. Cataracts: A cataract is a clouding of the lens in the eye that can cause blurry vision and increase the risk of glaucoma.
4. Glaucoma: This is a group of eye conditions that can damage the optic nerve and lead to vision loss.
5. Macular degeneration: This is a condition where the macula, the part of the retina responsible for central vision, deteriorates, leading to vision loss.
6. Diabetic retinopathy: This is a complication of diabetes that can damage the blood vessels in the retina and lead to vision loss.
7. Retinal detachment: This is a condition where the retina becomes separated from the underlying tissue, leading to vision loss.
8. Corneal abnormalities: These are irregularities in the shape or structure of the cornea, such as keratoconus, that can cause blurry vision.
9. Optic nerve disorders: These are conditions that affect the optic nerve, such as optic neuritis, that can cause vision loss.
10. Traumatic eye injuries: These are injuries to the eye or surrounding tissue that can cause vision loss or other eye abnormalities.

Eye abnormalities can be diagnosed through a comprehensive eye exam, which may include visual acuity tests, refraction tests, and imaging tests such as retinal photography or optical coherence tomography (OCT). Treatment for eye abnormalities depends on the specific condition and may include glasses or contact lenses, medication, surgery, or other therapies.
