Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Dear Authors,

Thank you for your manuscript titled "Arrhythmic Risk Stratification of Anderson-Fabry Disease: A Current Overview."

My comments are as follows:

1. The manuscript provides a broad narrative overview of the subject but does not focus as closely on the topic of arrhythmic risk stratification as suggested by the title. To improve alignment, I would recommend either refining the content to address arrhythmic risk stratification more directly or adjusting the title to reflect the scope of the review better.

2. To enhance the clarity and utility of your review, I suggest including a table that outlines the main parameters for defining arrhythmic risk in Anderson-Fabry disease, ordered by their importance. It would be helpful to cite relevant references for each parameter in the table.

3. If you wish to continue providing a more general narrative review on cardiovascular involvement in Fabry disease, I would recommend incorporating the following recent studies to enhance the comprehensiveness of your review further:

Reviewer 2 Report

Comments and Suggestions for Authors

I had the pleasure of reviewing Tognola et al.'s abstract about arrhythmia and Fabry Disease. The paper focuses on Anderson-Fabry disease (AFD), a rare disorder that causes arrhythmias and other organ issues. It reviews current methods for assessing arrhythmic risk, including diagnostic tools like echocardiography and ECG monitoring, as well as genetic markers. It also discusses treatments such as enzyme replacement therapy and antiarrhythmic drugs, while highlighting the importance of a multidisciplinary approach to improve patient care and outcomes. This is a very good manuscript, and I have some small comments and suggestions.

Major comments:

  • I would suggest combining some of the tables about cardiac follow-up for patients. Proband's on enzyme replacement therapy (ERT) usually have a follow-up that is "mandatory" for the drug, which already includes annual (or biannual if <35 years) ECG and echocardiogram. Would the authors agree with this follow-up, or do you think, based on this review, there could be changes to it? What about cardiac MRI?

Smaller comments:

  1. "Mutation" is used throughout the text; this should be changed to "variant" to align with HGVS nomenclature.
  2. Gb3 has already been defined before line 65, so the parentheses can be removed.
  3. "Gene" should be italicized in line 175.
  4. Make sure it is clear in line 157 that these are pathogenic/likely pathogenic variants that diagnose a patient, and not just any variant.
  5. Line 162 lacks a reference.
  6. Line 158 refers to "Diagnosis" on Gene Reviews (https://www.ncbi.nlm.nih.gov/books/NBK1292/) for the correct diagnostic methodology, which might differ in males and females.
  7. Lines 323-325 seem like a very nice summary. Could this be moved earlier in the text?
  8. The conclusion is in a different font size.

Thank you very much for taking the time to review this manuscript. Please find the detailed responses below and the corresponding revisions in track changes in the re-submitted file.

Comments 1: I would suggest combining some of the tables about cardiac follow-up for patients. Proband's on enzyme replacement therapy (ERT) usually have a follow-up that is "mandatory" for the drug, which already includes annual (or biannual if <35 years) ECG and echocardiogram. Would the authors agree with this follow-up, or do you think, based on this review, there could be changes to it? What about cardiac MRI?

Response 1: Thank you for your suggestion. We have, accordingly, included a table showing recommended cardiac follow-up in patients undergoing ERT. Based on our review, we emphasize the role of cardiac MRI as an essential tool for early detection and monitoring disease progression. We have included this in the revised manuscript. Thank you for your valuable feedback.

Comments 2: "Mutation" is used throughout the text; this should be changed to "variant" to align with HGVS nomenclature. 

Response 2: We agree that using the term "variant" instead of "mutation" aligns better with HGVS nomenclature. We have, accordingly, replaced "mutation" with "variant" throughout the text to ensure consistency with current genetic terminology. Thank you for pointing this out.

Comments 3: Gb3 has already been defined before line 65, so the parentheses can be removed.

Response 3: We have removed the parentheses around 'Gb3,' as it has already been defined prior to this line. 

Comments 4: "Gene" should be italicized in line 175.

Response 4: We have italicized “Gene” in that line as suggested. 

Comment 5: Make sure it is clear in line 157 that these are pathogenic/likely pathogenic variants that diagnose a patient, and not just any variant.

Response 5: Thank you for your comment. We have clarified that the variants being discussed are pathogenic or likely pathogenic variants that are used to diagnose a patient, rather than any variant. This distinction has been emphasized to ensure the accuracy of the information.

Comment 6: Line 162 lacks a reference.

Response 6: Thank you for pointing this out. We have added the appropriate reference. 

Comment 7: Line 158 refers to "Diagnosis" on Gene Reviews (https://www.ncbi.nlm.nih.gov/books/NBK1292/) for the correct diagnostic methodology, which might differ in males and females.

Response 7: Thank you for your comment. We have revised this section with the reference recommended for the correct diagnostic methodology, highlighting the difference between males and females. 

Comment 8: Lines 323-325 seem like a very nice summary. Could this be moved earlier in the text?

Response 8: Thank you for your feedback. We have moved this section earlier in the text to enhance the flow and provide clarity at an earlier stage.

Comment 9: The conclusion is in a different font size.

Response 9: Thank you for pointing this out. We have corrected the font size issue in the conclusion to ensure consistency with the rest of the manuscript.
