with specific marker proteins in routine laboratories , in which nephelometric instrumentation is frequently available but manpower is limited and the expert knowledge required to interpret proteinuria is lacking. improved pyrogallol red-molybdate method for determining total urinary protein. Urinary protein as measured with a pyrogallol red-molybdate complex, manually and in a Hitachi 726 automated analyzer. Effects of low and high relative molecular protein mass on four methods for total protein determination in urine.

Diagnostic significance of SDS-PAA-electrophoresis of urinary proteins: different forms of proteinuria and their correlation to renal diseases. A new strategy for characterizing proteinuria and haematuria from a single pattern of defined proteins in urine. ward: graphically oriented report forms. Presentation of complex, interrelated laboratory data for electrophoresis/immunofixation, cerebrospinal fluid, and urinary protein profiles. The relationship between the renal clearance of creatinine and the apparent renal clearance of ␤-2-microglobulin in patients with normal and impaired kidney function. Quantification of proteinuria: a re-evaluation of the protein/creatinine ratio for elderly subjects. excretion of IgG and ␣(1)-microglobulin predicts clinical course better than extent of proteinuria in membranous nephropathy. Cystic fibrosis (CF) is the most common autosomal reces-sive disease in Caucasian populations and is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. The CFTR gene encodes a transmem-brane protein that forms a cAMP-regulated chloride channel. Wide variations in disease manifestations are observed among affected CF patients, and a multitude of disease-causing mutations have been found in the CFTR gene (1). In 97% of men with CF, bilateral congenital absence of the vas deferens (CBAVD) blocks the transport of spermatozoa from testicular structures to the distal genital tract, causing azoospermia (2). Infertility attributable to CBAVD does not necessarily coincide with other manifestations of CF. CBAVD accounts for ϳ1–2% of all male infertility and at least 6% of the cases of obstructive azoospermia. Isolated CBAVD patients carry either a CF mutation (⌬F508 in 16 – 83% of cases and R117H in 6 –29% of cases) and/or a 5T variant in intron 8 (12– 47% of patients), supporting the hypothesis that CBAVD represents a mild, primary genital form of CF (2–7). Three length variations of a polythymidine (polyT) tract within the splice …

Lung disease associated with the IVS8 5T allele of the CFTR gene.

Cystic fibrosis is caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene. The 5T allele in intron 8 (IVS8) causes abnormal splicing in the CFTR gene, and is associated with lung disease when it occurs in cis with a missense mutation in the CFTR gene, R117H. However, the 5T variant alone has not been reported to cause lung disease. We describe two adult female patients w...

P-192: The Study of Cystic Fibrosis Transmembrane Conductance Regulator Gene Mutations and Polymorphisms in Iranian Patients with Mayer Rokitansky Kuster Hauser Syndrome

Background: Mayer - Rokitansky - Kuster - Hauser (MRKH) syndrome is characterized by congenital aplasia of the uterus and the upper part of the vagina in women showing normal development of secondary sexual characteristics and a normal 46, XX karyotype. Congenital anomaly of the female genital tract, estimated to occur in approximately 1 in every 5,000 females. It is caused by a failure of deve...

Intron-8 polythymidine sequence in Australasian individuals with CF mutations R117H and R117C.

Compound heterozygotes for a severe cystic fibrosis transmembrane conductance regulator (CFTR) mutation and the R117H or R117C mutation (R117H/C) have clinical presentations that vary from classic cystic fibrosis (CF) to an incidental genetic finding. The aim of this study was to assess the influence of the intron-8 polythvmidine sequence (IVS8) on the relationship between genotype and phenotyp...

CFTR Mutations in Congenital Absence of Vas Deferens

A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...

Cystic fibrosis gene mutations and infertile men with primary testicular failure.

It has been proposed that the gene responsible for cystic fibrosis, called the cystic fibrosis transmembrane conductance regulator (CFTR) gene, may play an important role in the process of spermatogenesis. A group of azoospermic men with primary testicular failure underwent CFTR mutation analysis, including assessment of the intron 8 polythymidine tract (IVS8-T tract). An association was not fo...

Higher proportion of intact exon 9 CFTR mRNA in nasal epithelium compared with vas deferens.

The 5-thymidine (5T) variant of the cystic fibrosis transmembrane conductance regulator (CFTR) intron 8 polypyrimidine tract (IVS8-T tract) is the most frequent CFTR gene alteration identified in men with congenital bilateral absence of vas deferens (CBAVD). This alternative splicing variant gives rise to two transcripts, one normal with exon 9 intact and the other with in-frame deletion of exo...
