    2. recently Van Capele et al. evidenced that a second mutation (defined as severe, less severe or potentially less severe) did not seem to have an effect on the age of onset of the disease [22]. A homozygous status for this mutation has been shown to have a low frequency (maybe explained by a reduced or incomplete penetrance); however, patients homozygous for this mutation do not seem to differ, in their clinical phenotype variation, from heterozygotes [19].

    5. In the present study, we describe the clinical course and provide a molecular analysis of another 25 mainland Chinese patients with IOPD, and we identified c.2662G > T (p.Glu888X) as the most common mutation in northern Chinese patients.

      CountryOrigin: mainland China; 12 patients from southern China, 13 from northern China

      Ethnicity: Chinese

      Race: Chinese

      AgeRange: median age at symptom onset = 3.4mo, median age at diagnosis = 4.9mo

      TotalNumber: 25

      FamilyInfo: Parents of those individuals with mutations were sequenced

      NoFamily: n/a

      GroupAddInfo: all patients diagnosed with IOPD between 2013 and 2016 at Shanghai Children's Medical Center. Of the 24 untreated patients, non survived beyond 1.5yrs, only surviving (Patient 25) was 7mo at last follow-up.

      GroupPreviousTesting: IOPD diagnosed via reduced GAA enzyme activity in leukocytes or DBS (PMID: 16702880)

      GroupGenotypingMethod: DNA isolated from blood samples, coding exons (2-20) and intron/exon boundaries of GAA gene amplified via PCR (primers: PMID: 10338092), resulting DNA was sequenced with ABI3730XL sequencer then was analyzed with Mutation Survey or DNA Variant Analysis software, novel mutations were screened in 60 normal individuals (120 alleles) via direct sequencing and no novel variants were found among these suggesting those found in study patients are uncommon polymorphisms.

      fragments containing a mutation in the patients were amplified and sequenced for the corresponding parents

      Phylogenetic conservation of missense mutations analyzed with ClustalX program, and pathogenicity of novel variants predicited with MutationTaster, sorting intolerant from tolerant (SIFT), and PolyPhen-2

      Variant: NM_000152.4(GAA):c.2662G>T (p.Glu888Ter)

      this was identified (by present study) as the most common variant in northern Chinese patients, heterozygous for 5 patients, homozygous for one patient
