D Cosgrove, DT Meehan, JA Grunkemeyer, JM Kornak, R Sayers, WJ Hunter and GC Samuelson Department of Genetics, Boys Town National Research Hospital, Omaha, Nebraska 68131, USA. A mouse model for the autosomal form of Alport syndrome was produced. These mice develop a progressive glomerulonephritis with microhematuria and proteinuria, consistent with the human disease. End-stage renal disease develops at approximately 14 weeks of age. TEM analysis of the glomerular basement membranes (GBM) during development of renal pathology revealed focal multilaminated thickening and thinning beginning in the external capillary loops at 4 weeks and spreading throughout the GBM by 8 weeks.

White Dr. Barker's interests include the genetic basis of inherited susceptibility to disease in individuals and populations. One area of current research focus is on the disease genetics of type IV collagens, which are involved in susceptibility to renal failure, hearing loss and other pathological conditions caused by abnormal basement membranes. A second focus is on the contribution of specific genomic rearrangements to the etiology of sporadic breast cancer. High molecular weight DNA samples have been prepared from over 1000 sporadic breast tumors and these are being examined for rearrangements in specific genes for which changes in expression may contribute to the development of neoplasia.

Research entire www.onderzoekinformatie.nl site fuzzy match Print View Titel Moleculair genetisch en functioneel onderzoek naar de pathogenese van het syndroom van Alport en vormen van familiaire benigne hematurie Abstract The primary defect of Alport Syndrome (AS) and some forms of Familial Benign Hematuria (FBH) resides in type-IV collagen. How these defects are becoming manifest and which other factors play a role is studied in this project. The pathogenesis is studied by means of molecular genetic and functional analyses. This is important for diagnostics, prognosis and possibly treatment of the patients. Moreover, basic information is obtained on the normal (embryonic) development of the kidney. 1. Molecular genetic studies: Mutation detection in COL4 genes is labour-intensive and has a relatively low score of 50%. Therefore the DNA microarray technique is introduced in order to be able, in due time, to rapidly determine the complete COL4A5 sequence and to assess the genetic predisposition of an individual with more precision. With conventional techniques mutations in the COL4A3- and COL4A4-genes in autosomal AS and FBH are sought. In view of the prognosis it is of paramount importance to discriminate these genetically. 2. Functional studies: The primary COL4-defects cause a disturbance of other GBM proteins and possibly also of synthesis and degradation of GBM. These changes may reflect a pathogenic continuation of the embryonal situation. Through cDNA micro-arrays expression patterns of both basal membrane genes and regulating enzymes and factors will be determined. With Western blots and immunohistochemistry the proteins themselves will be monitored. Research material is an embryonic, manipulable kidney tissue model (metanephros), as well as kidney material from Alport patients and controls.

Extractions: For some couples, the birth of a child with significant birth defects or a serious medical condition is the first indication that one or both of the parents may carry a genetic mutation that may result in a genetic disorder for their children. Other individuals may know they carry genetic mutations because of other affected family members. Some couples have been tested for common genetic mutations such as cystic fibrosis or sickle cell anemia and are aware prior to conceiving a child that they are at risk of having a child with serious medical problems. In the past, once the diagnosis of a genetic disease was determined, parents could only be counseled about the risks of having a child with that specific disease. With the development of amniocentesis and chorionic villus sampling (pre-natal genetic testing) and the development of the ability to test the DNA (genes) of the fetus directly, a couple can know fairly early in pregnancy if their child will be affected with the disease. They then face the difficult decision of whether or not to terminate the pregnancy. The Human Genome Project has greatly expanded our knowledge of the exact molecular basis of many familial diseases. The list of diseases for which the specific mutation or mutations is known is growing daily.

Together with cases displaying typical features of recessive ATS, i.e. rapidly sex-independent progressive nephritis or parental consanguinity, the study included sporadic male and female patients who had tested negative for COL4A5 mutations. Our analysis of COL4A3 and COL4A4 resulted in the identification of many changes, among which only eight could be confidently considered pathogenic. None were in a homozygous state, which would have been useful to evaluate their role: in COL4A3 four mutations were found in compound heterozygotes and three in simple heterozygotes, as the single COL4A4 mutation. COL4A3 and COL4A4 mutations can be classified in two groups expected to cause either the production of an abnormal alpha-chain or to reduce its synthesis, and operationally sub-divided as to whether they are present alone likely autosomal dominant, or belong to compound heterozygous genotypes likely autosomal recessive. While in recessive cases both null- and abnormal-chain mutations are found, the dominant inheritance seems limited to mutations predicted to result in the production of an abnormal chain. This hypothesis agrees with the observation that the only reported autosomal dominant ATS family had a large in-frame deletion of the alpha3(IV) chain, resulting from the skipping of exon 21 (9).

Every human being carries an average of six to eight abnormal recessive genes. However, these genes do not cause cells to function abnormally unless two copies of an abnormal recessive gene are present. In the general population, the chance of a person having two copies of an abnormal recessive gene is very small, but in children of close relatives, the chances are higher. Chances are also high among groups that intermarry, such as the Amish or Mennonites. An abnormal gene may be inherited or may arise spontaneously as a result of a mutation (a sudden change in a gene arising as a result of any one of a number of causes or for no apparent cause at all). Depending on whether the mutation affects the reproductive cells or not, the mutation may be passed on to future generations or may simply die out with the person who has the mutation.
