Topic: Von Hippel Landau Disease
Symptoms: Include a discussion of symptoms in individuals heterozygous vs. homozygous for the defective gene if appropriate.
Von Hippel-Lindau syndrome is caused by heterozygous mutation in the VHL gene
The symptoms of von Hippel-Lindau syndrome are angiomata of the retina (i.e. a tumor consisting of a mass of blood vessels in the retina) and hemangioblastoma (i.e. a tumor) of the cerebellum. There also may be a tumor - Hemangioma in the spinal cord. Pheochromocytoma occurs in some patients. This is indicated by one or more of the following symptoms:
Skin sensations
Flank pain
Elevated heart rate
Elevated blood pressure,
Palpitations
Anxiety often resembling that of a panic attack
Diaphoresis (excessive sweating)
Headaches
Pallor
Weight loss
The most common symptoms are headache, excessive sweating, and increased heart rate. The combination of hypertension with angioma may lead to subarachnoid hemorrhage (i.e. bleeding in the brain).
People with the syndrome also commonly develop cysts in the kidneys, pancreas, and genital tract.
About 10% of people with the disease develop noncancerous tumors in the ear which can lead to loss of hearing in the ear as well as ringing in the ears (tinnitus) and loss of balance. (Genetics Home Ref. Von Hippel-Lindau syndrome)

There are fewer symptoms for this type than NF1. There are fewer brown spots on the body. This disorder is noted for the frequency of tumors found on the spinal cord and brain. These tumors more often than not cause loss of hearing or a ringing sounds to occur in the ears.

This disease is noticeable by the age of 6 to 12 months. Parental DNA pattern test is a test
This syndrome is diagnosed because of a few different factors. It is diagnosed when one has multiple tumors in the brain, spinal cord, or eye. Even if one

Sturge-Weber syndrome is also called "encephalotrigeminal angiomatosis." It is a congenital disorder. It causes a vascular birthmark and neurological abnormalities.
A child with this disorder can suffer from a number of symptoms. The mutation cause symptoms like weak muscle tone, delayed motor skill developed, and delayed or absence of puberty. Only male persons can have this disorder and are more likely to have severe cryptic acne during adolescence. A male

People with the genetic condition have distinctive facial features, experience sleep problems, feeding issues, growth and developmental delays. The 5-year-old also has branch pulmonary stenosis, which is a heart condition.
Signs and symptoms include muscle spasms, epilepsy, intellectual disability, hypotonia, microcephaly, microopthalmia, colobomas (incomplete development of the retina and optic nerve), musculoskeletal abnormalities (“Aicardi syndrome - NORD (national organization for rare disorders),” n.d.), Hypertonia
Those with a mutated gene have significantly increased risk of developing hemangioblastomas, which are blood vessel tumors of the brain, spinal cord, eye which are called retinal angiomas, clear cell renal cell carcinoma, which is a specific type of kidney cancer; and pheochromocytoma, which is a tumor of the adrenal gland. Kidney cysts, which are closed sacs usually filled with fluid; pancreatic cysts, epididymal cystadenomas, and endolymphatic sac tumors, which are tumors of the ear that may cause hearing loss; are also features of VHL [1].
Von Hippel-Lindau Syndrome is a genetic disorder. It is a hereditary condition which is associated with hemangioblastomas, which are blood vessel tumors of the brain, spinal cord, and eyes. Some of the symptoms of Von Hippel-Lindau Syndrome (VHL) can be increased risks of kidney cancer and even blood vessel tumors of the brain, spinal cord, and eyes.
Foremost, if anyone else, including our family, has this genetic mutation would show these symptoms:
The diagnosis of the disease, its cause or causes, stage, treatment and prognosis will be sought from the pediatrician. He establishes and explains the connection between the disease and the patient's family history. He prescribes appropriate medicines and medications to alleviate the patient's symptoms. The moral principles surrounding the couple's decision concerning the disease are contributed by the ethicist. He warns against the double-effect situation in this disease condition. He emphasizes that birth defects
