## Summary

E656del is an in-frame variant in GAA: it adds or removes one or more amino acids without shifting how the rest of the gene's code is read. ClinVar classifies it as pathogenic for Pompe Disease (Glycogen Storage Disease II) (reviewed by expert panel).

## Limitations

This page describes publicly available information about a genetic variant. It is not a diagnosis, and it says nothing about whether you or anyone else carries this variant.

Classifications come from ClinVar and change as new evidence is reviewed. A classification here may differ from the one in ClinVar today, or from the one a laboratory reports.

Whole genome sequencing with short reads can miss or miscall some variants, particularly in repeated or highly similar stretches of DNA and in large insertions, deletions or rearrangements.

If you have questions about a variant in your own results or in your family, talk to a genetic counsellor or your doctor.
