gives 1,2% residual activity in expression study - causes exon 9 skip
weakens exon 9 splice donor
detection of leaky wildtype splicing
unknown

Class C25 (GV: 32.40 - GD: 65.72)

The Pompe disease GAA variant database represents an effort to collect all known variants in the GAA gene and is maintained and provide by the Pompe center, Erasmus MC.
