BACKGROUND Pediatric autoinflammatory diseases are rare and still poorly understood conditions resulting from defective genetic control of innate immune system, inter alia from anomalies of NOD2 gene. The product of this gene is Nod2 protein, taking part in maintenance of immune homeostasis. Clinical form of resultant autoinflammatory condition depends on NOD2 genotype; usually patients with NO...

Pouchitis is common in ulcerative colitis patients undergoing total proctocolectomy with ileal pouch-anal anastomosis, and chronic antibiotic-refractory pouchitis occurs in a subgroup of the patients. Auto-inflammatory diseases are characterized by systemic inflammation, manifesting as periodic fever, rash, arthritis, and serositis. We describe two cases with ulcerative colitis and an ileal pou...

The Smith-Lemli-Opitz syndrome (SLOS) is an inborn disorder of sterol metabolism with characteristic congenital malformations and dysmorphias. All patients suffer from mental retardation. Here we identify the SLOS gene as a Delta7-sterol reductase (DHCR7, EC 1.3.1. 21) required for the de novo biosynthesis of cholesterol. The human and murine genes were characterized and assigned to syntenic re...

The involvement of the five thymidine (5T) variant in intron 8 of the cystic fibrosis membrane regulator (CFTR) gene in congenital bilateral absence of the vas deferens (CBAVD) phenotype has been extensively demonstrated. This variant leads to alternative splicing of the CFTR gene which results in a wild-type transcript and one without exon 9. Little is known about expression of the CFTR gene i...

Sequencing of all 27 CFTR exons, including flanking intronic regions, and a search for large rearrangements were undertaken in the remaining 18 DNA samples. Calling all the patients back for further familial genetic studies could not be considered and we assumed that two identified mutations are located in trans. ORs were calculated and proportions were compared with prior probability using the...

The human HPRT gene contains spans approximately 42,000 base pairs in genomic DNA, has a mRNA of approximately 900 bases and a protein coding sequence of 657 bases (initiation codon AUG to termination codon UAA). This coding sequence is distributed into 9 exons ranging from 18 (exon 5) to 184 (exon 3) base pairs. Intron sizes range from 170 (intron 7) to 13,075 (intron 1) base pairs. In a datab...

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 auto...
