Profile of patients with Von Gierke disease from India.

Molecular diagnosis of Von Gierke disease is possible by mutation analysis of G6PC gene. GSD type 1a cases account for 20 % of glycogenoses in our center. We diagnosed ten unrelated patients with glycogen storage disease based on clinical, biochemical and histopathology investigations. Mutation analysis was done by sequencing the G6PC gene. Two unrelated patients were found to be homozygous for a novel mutation c.355 C >; G (p.H119D). They were born to non-consanguineous parents from Karnataka. This suggests founder effect. Mutation detection confirms the diagnosis and assists in counseling and prenatal diagnosis.
