Two new mutations in children affected by partial biotinidase deficiency ascertained by newborn screening

J Inherit Metab Dis. 2002 Aug;25(4):328-30. doi: 10.1023/a:1016522912849.

Abstract

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.
