Review for 10.1186/s12876-021-01756-y (2021)

Reviewer’s report
Title: 
Characterization of novel and large fragment deletion s  in exon 1 of the
IL10RA 
 gene in Chinese children with very early onset inflammatory bowel
diseases
Version: 
1 
Date: 
29 Oct 2020
Reviewer's report:
An interesting and valuable study on very early onset IBD. It would be better
and much more beneficial for the clinicians if these 5 patients with large
deletions in Exon1 were compared with other patients and their differences and
similarities were revealed.
Also, there are English errors in some sentences including the title sentence.
