Two new mutations in children affected by partial biotinidase deficiency ascertained by newborn screening.
Mutation analysis performed on DNA from 6 Italian patients with partial biotinidase deficiency ascertained by newborn screening allowed the identification of two new mutations, c1211C > T (T404I) and a single base deletion c594delC. All patients were compound heterozygous for the D444H amino acid substitution showing that this mutation is also common in Italian patients affected by partial biotinidase deficiency.
