Beschreibung
Alport syndrome is a genetic condition characterised by kidney disease, hearing loss, and eye abnormalities.
People with Alport syndrome experience progressive loss of kidney function. Almost all affected individuals have blood in their urine (hematuria), which indicates abnormal functioning of the kidneys. Many people with Alport syndrome also develop high levels of protein in their urine (proteinuria). The kidneys gradually lose their ability to efficiently remove waste products from the body, resulting in end-stage kidney disease (ESKD).
In late childhood or early adolescence, many people with Alport syndrome develop sensorineural hearing loss, which is caused by abnormalities of the inner ear. Affected individuals may also have misshapen lenses in their eyes (anterior lenticonus) and abnormal coloration of the retina, which is the light-sensitive tissue at the back of the eye. These eye abnormalities seldom lead to vision loss.
Inheritance patterns
The source lists the following possible inheritance patterns: Autosomal recessive; Autosomal dominant; X-linked. More than one pattern can apply in different cases.

Down-Syndrom-Screening
There are two different types of tests that can be done to look for Down's syndrome during pregnancy - a screening test and a diagnostic test. Down's syndrome is a genetic chromosome problem that some people are born with. This involves a blood test for levels of: Alpha-fetoprotein (AFP). Again, a computer program is used to give the chance of the.

Überaktives Blasensyndrom
Überaktives Blasensyndrom is very common. Symptoms of overactive bladder include an urgent feeling that you need to go to the toilet, needing to pass urine frequently and sometimes leaking urine before you can get to the toilet. Overactive bladder (OAB) syndrome means that the bladder, which is a bag made von muscle, squeezes (contracts) suddenly.

Nephrotisches Syndrom
Nephrotisches Syndrom is a condition where the 'filters' in the kidney become 'leaky' and large amounts of protein leak from the blood into the urine. The main symptom is fluid retention (oedema) which is mainly due to the low protein level in the blood. Various diseases can cause nephrotic syndrome, some more serious than others. The most common.
