摘要: The clinical presentation and laboratory findings in seven patients with neonatal/infantile-onset galactosialidosis are presented. We detected no carboxypeptidase activity two of these patients, while an enzyme different apparent Km, or both Km Vm, were found five others. could not establish a correlation between the biochemical characteristics age onset, progression, other features galactosialidosis.
