A screening method for biotinidase
deficiency in newborns.
Can you possibly conceive of a parent taking their baby home from the hospital ready to tackle the challenges of parenthood not knowing that he or she had biotinidase
deficiency; then finding out four or six months later that their son or daughter was destined for a life with severe intellectual disabilities?
This mass shift corresponded to the loss of the biotin-tag cleaved off enzymatically by biotinidase
The other tests that make up the March of Dimes recommended core list are: phenylketonuria (PKU); congenital hypothyroidism; congenital adrenal hyperplaisa (CAH); galactosemia, biotinidase
deficiency; maple syrup urine disease; sickle cell anemia; and hearing screening.
Direct analysis of enzyme activity is used in testing for galactosemia (galactose-1-phosphate uridyltransferase deficiency) and biotinidase
The March of Dimes Pennsylvania Chapter is poised to introduce legislation that will add Homocystinuria, Biotinidase
Deficiency, and Medium-Chain ACYL-COA Dehydrogenase Deficiency (MCAD) to the newborn screening tests already offered in the state to bring Pennsylvania to the nine core metabolic tests recommended by the March of Dimes.
The most common inborn errors of metabolism being screened by states and territories include PKU, hypothyroidism, galactosemia, bio biotinidase
deficiency, congenital hypothyroidism, and maple syrup urine disease.
Defects in processing of the cofactor for PCC, biotin, could in theory lead to C3-carnitine elevation, but isolated elevations of C3carnitine in patients with biotinidase
deficiency or holocarboxylase synthetase deficiency have not been reported.

In most Caucasian populations, the incidence is lower, ~1 in 100 000 births, which equals the frequency of biotinidase
Neonatal screening with the SPOTCHECK automated chemistry analyzer includes tests for phenylalanine, total galactose, uridyltransferase, tyrosine, biotinidase
deficiency and G6PD deficiency.
