Reviewer's report:  
 
This case is a report of protein losing enteropathy of Noonan syndrome, and considered as a 
valuable report.  
 
However, I would like you t o consider the following points.  
 
1. In this case, dietary therapy has been useful for reducing edema.  
 
Please consider dietary treatment for protein losing enteropathy (low fat diet, etc.)  
 
 
2. Endoscopic images are not enough quality and the snowflake appe arance that the author 
considers important is unclear. Please improve image quality and point important findings with 
arrows. Please use the arrows etc. for CT images to match the findings and figure legends.  
 
 
3. In figure2, the patient number of II2 is in correct. Also, please add a description of the gene 
mutation part so that it is easier to understand.  
 
I think that it is necessary to add explanation also about figure3.
