The COL4A5 gene encodes the alpha5 (type IV) collagen chain and is defective in X-linked Alport syndrome (AS). Here, we report the first systematic analysis of all 51 exons of COL4A5 gene in a series of 201 Italian AS patients. We have previously reported nine major rearrangements, as well as 18 small mutations identified in the same patient series by SSCP(More)
Incontinentia pigmenti (IP), or "Bloch-Sulzberger syndrome," is an X-linked dominant disorder characterized by abnormalities of skin, teeth, hair, and eyes; skewed X-inactivation; and recurrent miscarriages of male fetuses. IP results from mutations in the gene for NF-kappaB essential modulator (NEMO), with deletion of exons 4-10 of NEMO accounting for >80%(More)
BACKGROUND IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and is characterized by extremely variable clinical and morphological features and outcome. TGF-beta1 has a key role in fibrogenesis and the progression of renal damage. Its production is under genetic control. METHODS We recruited 105 Italian biopsy-proven IgAN(More)
We describe a family with autosomal dominant polycystic kidney disease in which molecular typing with closely linked markers for the PKD1 and PKD2 genes indicated absence of linkage. Thus, a third still unknown locus appears likely to be involved in disease development. This is the fourth "PKD3-linked" family described to date and the first from Italy.
Polycystin-1 and polycystin-2 are the products of PKD1 and PKD2, genes that are mutated in most cases of autosomal dominant polycystic kidney disease. Polycystin-2 shares approximately 46% homology with pore-forming domains of a number of cation channels. It has been suggested that polycystin-2 may function as a subunit of an ion channel whose activity is(More)
Cleavage fragment length polymorphism analysis with silver staining visualization (CFLPA-SS) was used for the detection of mutations previously detected by single strand conformation (SSCA) or heteroduplex analyses (HA); in order to assess this new method for mutation screening. The analysed mutations include single nucleotide transitions, transversions, a(More)
Adult polycystic kidney disease (APKD) is a frequent disease (1/1000) responsible for about 10% of chronic renal failure. It is an autosomic dominant disease due to mutation of one out of three genes: PKD1 (on the 16th chromosome), PKD2 (on the 4th chromosome) and PKD3 (still unmapped). In the past APKD diagnosis was normally done in fourteen-fifteen years(More)
Solid organ transplant recipients are at higher risk of non-melanoma skin cancer (NMSC), especially basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Genetic alterations in the production of detoxifying enzymes such as glutathione S-transferase (GST) and CYP1A1 may enhance this risk. We investigated the frequency of GST genotypes (GSTM1, GSTM3,(More)
BACKGROUND Overexpression of cyclooxygenase-2 (COX-2), resulting in excessive prostaglandin production, has been observed in human epidermal keratinocytes after ultraviolet B injury, in squamous cell skin carcinoma (SCC), in actinic keratoses, and in the early stages of carcinogenesis in a wide variety of tissues. The dysregulation of COX-2 expression can(More)
In clinical research, many potentially useful variables are available via the routine activity of cancer center-based clinical registries (CCCR). We present the experience of the breast cancer clinical registry at Fondazione IRCCS "Istituto Nazionale dei Tumori" to give an example of how a CCCR can be planned, implemented, and used. Five criteria were taken(More)
