CaseAddInfo: Adult Late Onset Pompe Disease

Case31

HPOsFreeText: See Group Phenotypes

CasePreviousTesting: Sanger sequencing

CaseMethod1: Sanger sequencing and PCR Amplification

CaseMethod2: Whole Exome Sequencing (WES)

CaseGenotypingMethod: Patients were previously confirmed with Pompe disease by Sanger sequencing to capture the pathogenic variants. The process was repeated as part of the study taking care to amplify the coding regions and exon/intron boundaries to compare with the WES results afterwards.
