Introduction Biotinidase deficiency is a life threatening inborn error of metabolism specially when delayed in diagnosis. We report a 2-month-old male infant that presented with refractory infantile spasm, alopecia and seborrheic dermatitis. With a high suspicion of the biotinidase deficiency we started biotin 10 mg daily orally before definite diagnosis was made. Rapid treatment was life-savin...

Acutepancreatitis can infrequently be a life-threatening complication of hypertriglyceridemia. Rarely, hypertriglyceridemia can originate from an inborn genetic error in lipoproteins metabolism. This condition can be manifested by very high serum triglyceride levels (>1000 mg/dl) and a more severe and lethal form of pancreatitis. Here, we present a case of acute pancreatic which was found out t...

Phenylketonuria is an autosomal recessive inborn error of metabolism which can be prevented by early and continuous treatment. Therefore newborn screening for phenylketonuria has been introduced in many countries. We present here the results of the selective newborn screening for inborn errors of metabolism, including PKU, performed by tandem mass spectrometry which has been introduced in Maced...

phenylketonuria (pku) is an inborn error of amino acid metabolism with an autosomal recessive inheritance caused in most cases by mutations in the phenylalanine hydroxylase (pah) gene. pku has wide allelic heterogeneity. here we report a novel heterozygous substitution (c.1223g>t (p.arg408leu)) in the pah gene in an iranian pku family. the patient was 19-yr-old female with diagnosis of moderate...

Inborn errors of metabolism (IEMs) are known for their low prevalence and multidisciplinary care mostly founded on expert opinion. Clinical pathways are multidisciplinary tools to organise care which provide a clear route to the best care and improve communication. In 2010 the Dutch Society for Children and Adults with an Inborn Error of Metabolism (VKS) initiated development of clinical pathwa...
