URL Parameter Syntax

EmVClass may be automatically searched using the argument [approved_symbol] such as in the example link for the gene CFTR: https://www.egl-eurofins.com/emvclass/emvclass.php?approved_symbol=CFTR


EmVClass data for all genes and variants that have been seen and analyzed by NTD Genetics may be downloaded as a CSV plain text file which is designated to be updated quarterly. Data is subject to change and format is subject to modification.



The interpretation of nucleotide changes is based on our current understanding of the variant at the time it was observed in a clinical case. Interpretations may not be current. Some data may not be represented. These interpretations may change over time as more information about the genes becomes available. The data presented here are not intended for clinical use outside of the context of an official NTD Genetics clinical report and should be approached with caution. Only variants identified at NTD Genetics are listed in the EmVClass. If you intend to use NTD Genetics' classification for publication purposes please contact the laboratory for permission.
