Glycogen storage disease type Ib: the first case in Taiwan.
Glycogen storage disease (GSD) type Ib is caused by the deficiency of glucose-6-phosphate translocase activity. The elder brother of the proband died at age 20 months, and GSD Ia, a disease caused by the deficiency of glucose-6-phosphatase, was the diagnosis. Theproband developed hypoglycemia shortly after birth. Dietary therapy was instituted immediately, but his growth was poor and there were repeated episodes of pyogenic infection. Neutropenia had been observed since 6 months of age, but the diagnosis of GSD Ib was established only at 18 months of age two mutations (c.354_355insC (p. W118fsX12) and c.736T>C (p.W246R)) were detected on his SLC37A4 gene. Regular administration of G-CSF rapidly improved his health and decreased his hospital stay. Although GSD Ib is very rare in Taiwan, correct diagnosis is essential to save the lives of such patients.
