The disorder may also include eye defects. Causes, incidence, and risk factors Return to top Alport syndrome is very similar to hereditary nephritis. There may be nerve deafness and congenital eye abnormalities associated with Alport syndrome. The cause is a mutation in a gene for collagen. The disorder is uncommon, and most often affects males since the genetic defect is typically found on the X chromosome. In women, the disorder is usually mild, with minimal or no symptoms. Women can transmit the gene for the disorder to their children, even if the woman has no symptoms of the disorder. In men, the symptoms are more severe and progress faster.

3. Alport Workshop The Fourth International Workshop on alport syndrome. This Fourth International Workshop on alport syndrome was held in Salt Lake City April 1517, 1999. http://www.cc.utah.edu/~cla6202/ASIW.htm

The Fourth International Workshop on Alport Syndrome April 15-17, 1999 Salt Lake City, Utah, USA Dear Colleagues and Alport Families: The first afternoon was devoted to the first-ever session for patients and families. Conducted by six of us from University of Utah and Primary Children's Hospital, it was attended by one Australian, four Canadians, one Cypriot, two Turks, eight other Utahns, and 21 persons from ten other U.S. states. The program with hyperlinks is shown below. An audiotape of this session only is being edited and may eventually become available via the Hereditary Nephritis Foundation and/or the National Kidney Foundation of Utah The subsequent two days were devoted to scientific sessions. Programs are given below. This Workshop was attended by four of us from University of Utah and by 42 others representing at least 18 nationalities. Attendees proposed to form an International Consortium on Alport Syndrome, along the lines of the existing European Consortium. The next International Workshop on Alport Syndrome and Other Inherited Glomerular Diseases will be held in Europe in the autumn of 2001, likely in Stockholm. Tentatively, a further workshop will be held in Australia in 2004, in conjunction with the International Pediatric Nephrology Association Meetings.

Alport Syndrome Alport Syndrome is an inherited disease that affects the glomeruli, the tiny blood vessels within the kidneys that filter the blood of its wastes. It was first described by an English doctor, A. Cecil Alport. Because of the way Alport Syndrome is inherited, the disease tends to be more severe in men than in women. What are the symptoms? The central feature of the disease is the presence of blood in the urine. Boys with Alport Syndrome develop this symptom in infancy, while girls who carry the Alport gene may or may not have it. Another important symptom of Alport Syndrome is hearing loss. In boys with the disease, hearing loss is usually detectable by 8-10 years of age, and it may be severe enough to require the use of hearing aids. Hearing loss in girls tends to be much milder, rarely resulting in the need for hearing aids. Some boys with Alport Syndrome lose large amounts of protein in the urine, resulting in retention of fluid and body swelling. This condition is called "the nephrotic syndrome." With the passage of years, boys with Alport Syndrome develop the typical signs and symptoms of kidney failurehigh blood pressure, swelling, and in some cases, impaired growth. Some people with Alport Syndrome have an eye problem called anterior lenticonus, in which the shape of the lens becomes distorted. This can interfere with the sharpness of vision.

Background This is a rare inherited disease that chiefly affects the kidneys. It is caused by mutations in one or the other of several COL4A genes. These genes encode for the elements of the basement membrane (Type IV) collagen. The result is a hereditary glomerulonephritis with a chronic nephritis that progresses to end-stage renal disease. Associated conditions include hearing loss, lenticonus and other eye disorders, immunologic abnormality of skin, disorders of platelets, abnormalities of white blood cells, and smooth muscle tumors.

The disorder causes chronic glomerulonephritis with destruction of the glomeruli in the kidneys. Initially, there are no symptoms. Progressive destruction of the glomeruli causes blood in the urine and decreases the effectiveness of the kidney's filtering system.

Profile Programs Volunteering Offices ... Main Page Alport Syndrome Alport Syndrome (AS) is an inherited disorder of the basement membranes of the kidney, eye and ear. People who inherit defective genes for the "collagen" proteins in these basement membranes may develop progressive loss of renal function, deafness and abnormalities of the eye. In the kidneys, glomerular basement membranes normally act like filters, allowing fluid to move from blood vessels to urine while retaining protein and red blood cells within the bloodstream. Thus, one of the early signs of Alport syndrome may be leakage of small amounts of blood or protein into the urine during childhood. Collagen-containing membranes are also important for the shape of the lens of the eye and the structure of the inner ear. History In 1927, Dr. Alport wrote his classic report on a British family with the syndrome. He drew attention to the fact that affected males in this family uniformly developed progressive renal failure and deafness, whereas females were less affected. This pattern of inheritance is termed "X-linked". The normal copy of the gene onto the other X chromosome relatively protects female "carriers" who inherit an abnormal Alport gene on one X chromosome. Some females may develop renal insufficiency, but in general this occurs late in life. In contrast, every male receives one Y chromosome from his father and one X chromosome from his mother; thus, if he happens to inherit an X-chromosome bearing a mutant Alport gene, the boy is unprotected and develops the full-blown Alport Syndrome as a young adult.

Turkington Definition A hereditary disease of the kidneys that primarily affects men, causing blood in the urine, hearing loss and eye problems. Eventually, kidney dialysis or transplant may be necessary. Description Alport syndrome affects about one in 5,000 Americans, striking men more often and severely than women. There are several varieties of the syndrome, some occurring in childhood and others not causing symptoms until men reach their 20s or 30s. All varieties of the syndrome are characterized by kidney disease that usually progresses to chronic kidney failure and by uremia (the presence of excessive amounts of urea and other waste products in the blood). Causes and symptoms Alport syndrome in most cases is caused by a defect in one or more genes located on the X chromosome. It is usually inherited from the mother, who is a normal carrier. However, in up to 20% of cases there is no family history of the disorder. In these cases, there appears to be a spontaneous genetic mutation causing Alport syndrome. Blood in the urine (hematuria) is a hallmark of Alport syndrome. Other symptoms that may appear in varying combinations include:

Is there anything I can do to keep their kidney's healthy? Please may I have some general information about the disease? Answer Alport syndrome is the most common of several types of what are called hereditary nephritis. Nephritis is a non-specific term to describe inlfammation of the kidneys which can result from a number of different causes. Alport syndrome shows marked variation in the symptoms which occur, the course of the disease, the underlying problem with the cells of the kidney, and the way in which it is inherited. Those with Alport syndrome often have no symptoms, but microscopic amounts of blood are found in their urine if it is examined. They sometimes have large amounts of blood in the urine which can be seen.

Alport syndrome from EdREN , the website of the Renal Unit of the Royal Infirmary of Edinburgh What happens in Alport syndrome? What trouble does Alport syndrome cause? How is it inherited? How can family members tell whether they have Alport syndrome? ... Key points Alport syndrome is the second most common inherited cause of kidney failure. It usually affects young men, but it can affect older people and women. What happens in Alport syndrome? In each of the one million tiny filtering units (glomeruli) in each kidney, blood is filtered across the glomerular basement membrane (GBM). In Alport syndrome, type IV collagen, one of the proteins that makes up the GBM, is absent or abnormal. Althought the GBM looks normal in childhood, the GBM deteriorates with time because it lacks the special type IV collagen that should be there, (see pictures). Normal Alport A very highly enlarged view of the filter in the glomerulus. These electron microscope images are magnified x100,000, and show glomerular basement membrane ( G ) in a normal glomerulus (LEFT) and in Alport syndrome (RIGHT). The diagrams below illustrate the thickening and 'falling apart' of Alport GBM.

May-Hegglin anomaly is the same as Sebastian syndrome but with structurally different wbc inclusions. Check any of these in OMIM Thin basement membrane disease Ad Basement membrane collagen. Probably a minority of families are carriers of autosomal recessive Alport syndrome, but a significant proportion are. Unlike female carriers of COL4A5 mutations, there are not areas of thickening/ basket weave, just global thinning of the GBM.

Genetics and Deafness - Alport Syndrome Alport Syndrome (AS) is characterized by hereditary nephritis (kidney disease known as Bright's disease in the past) and sensorineural hearing loss. The mode of inheritance may be X-linked or autosomal dominant. Less common symptoms include a defect of the lens of the eye called anterior lenticonus and a defect of blood platelets that can cause bleeding complications. AS is usually diagnosed by a test for blood and protein in the urine, hearing tests, and an extended family history. Hearing loss commonly occurs in childhood. - Most subtypes of AS include a bilateral progressive sensorineural hearing loss of mild to moderate degree, but some individuals may have a severe to profound loss. Females generally have a milder hearing loss than their male relatives if they have one at all. Management of the hearing loss includes regular audiologic follow-up, use of hearing aides, and avoidance of certain drugs and excessive noise exposure that can cause further hearing loss.
