Holocarboxylase synthetase (HLCS) deficiency (HLCSD) is a rare autosomal recessive disorder of biotin metabolism. HLCS catalyzes the biotinylation of the four human biotin-dependent carboxylases. Using the newly available human genomic sequence, we report the map of HLCS genomic structure and the predicted exon/intron boundaries. Moreover, the molecular(More)
Linezolid is a new drug from the oxazolidinone class of antibiotics used against mycobacteria and multi-drug resistant (MDR) Gram-positive bacterial infections, which may are also glycopeptide-resistant. The drug usage in pediatric age needs an accurate drug monitoring for effective patient management. The aim of this study was to evaluate the use of dried(More)
BACKGROUND Barth syndrome (BS) is an X-linked infantile-onset cardioskeletal disease characterized by cardiomyopathy, hypotonia, growth delay, neutropenia and 3-methylglutaconic aciduria. It is caused by mutations in the TAZ gene encoding tafazzin, a protein involved in the metabolism of cardiolipin, a mitochondrial-specific phospholipid involved in(More)
Tyrosinemia type I is a genetic disorder characterized by accumulation in the blood and urine of the toxic metabolite succinylacetone (SUAC), not detectable in healthy samples. In many countries, newborns are screened for tyrosinemia type I using tyrosine as a primary marker. Unfortunately, tyrosine accumulation may take longer to occur and it may be not(More)
3-Hydroxy-3-methylglutaric aciduria is a rare autosomal recessive inborn error of metabolism caused by deficiency of the mitochondrial enzyme 3-hydroxy-3-methylglutaryl-CoA lyase (HMGCL). Up to now only a few mutations have been reported in the HMGCL gene. We report the first Italian patient, a female who presented metabolic acidosis at 3 days of age and(More)
BACKGROUND Adenosine deaminase (ADA)-severe combined immunodeficiency (SCID) is caused by genetic variants that disrupt the function of ADA. In its early-onset form, it is rapidly fatal to infants. Delayed or late-onset ADA-SCID is characterized by insidious progressive immunodeficiency that leads to permanent organ damage or death. Quantification of T-cell(More)
BACKGROUND Purine nucleoside phosphorylase (PNP) deficiency is a rare form of autosomal recessive combined primary immunodeficiency caused by a enzyme defect leading to the accumulation of inosine, 2'-deoxy-inosine (dIno), guanosine, and 2'-deoxy-guanosine (dGuo) in all cells, especially lymphocytes. Treatments are available and curative for PNP deficiency,(More)
We investigated the role of low molecular weight (LMW) and high molecular weight (HMW) isoforms of basic fibroblast growth factor 2 (FGF-2) in the expression of transformation-related phenotypic alterations, drug sensitivity modulation, and gene amplification potential. For this purpose, we used NIH 3T3 and A31 cells transfected with different cDNA FGF-2(More)
Carbamyl Phosphate Synthetase I deficiency (CPSID) is a rare autosomal recessive urea cycle disorder usually characterized by potentially lethal neonatal hyperammonemia. The large (5215 bp) CPS1-cDNA, expressed only in liver and epithelial cells of intestinal mucosa, has been cloned. Until now the CPS1 genomic organization was unknown. Taking advantage of(More)
BACKGROUND X-linked Ornithine Transcarbamylase deficiency (OTCD) is often unrecognized in adults, as clinical manifestations are non-specific, often episodic and unmasked by precipitants, and laboratory findings can be normal outside the acute phase. It may thus be associated with significant mortality if not promptly recognized and treated. The aim of this(More)
