suggesting that it was a recurrent mutation, not caused by a founder
effect.
Two novel mutations including a missense (c.1204T4C, p.Y402H)
and a mutation in the termination codon (c.1609T4C, p.X537A)
were identified. A splice site mutation previously reported in a Thai
patient with type 3 GD,11 the IVS6-1G4C change, was compound
heterozygous with the c.1609T4C (p.X537A) in patient 5.
Sequencing of his cDNA showed no skipping around IVS6 and
only the C at position 1609 (Figure 1c lower panel), suggesting that it
