The national neonatal screening programme in the United Arab Emirates currently includes 16 disorders: congenital hypothyroidism, sickle-cell diseases, congenital adrenal hyperplasia, biotinidase deficiency and 12 amino acid, organic acid and fatty acid disorders. This paper reports data since the programme started in January 1995 up to December 2011 on the incidence of screened disorders and t...

The BTD gene codes for production of biotinidase, the enzyme responsible for helping the body reuse and recycle the biotin found in foods. Biotinidase deficiency is an autosomal recessively inherited disorder resulting in the inability to recycle the vitamin biotin and affects approximately 1 in 60,000 newborns. If untreated, the depletion of intracellular biotin leads to impaired activities of...

Biotinidase deficiency (BTD) is a rare inherited metabolic disorder with predominant dermatogical and neurological manifestations, which if untreated leads to severe sequelae. Early diagnosis prompt treatment biotin prevents further progression of symptoms resolution cutaneous features. We report an interesting case four half year male child presenting seizures, developmental delay non resolvin...

Screening programs for late-onset, biotin-responsive, multiple carboxylase deficiency (LMCD) detect colormetrically the presence of biotinidase activity in dried samples of whole-blood spotted on filter-papers as used in the neonatal screening of phenylketonuria. A sensitive and stable qualitative technique is described using 10 microliter of serum that avoids problems associated with poor samp...

Biotinidase (BTD) enzyme deficiency is a congenital metabolic disorder with autosomal recessive inheritance. Main symptoms in its are nervous system and skin manifestations. A 15-month-old patient who was diagnosed Li-Campeau syndrome, also BTD his clinic rapidly improved biotin treatment. With the awareness of different clinical presentations deficiency, patients presenting raising suspicion t...
