 ### Main functional consequences
 
 1. ![](https://placehold.it/15/D43925/000000?text=+) **Predicted loss-of-function (pLoF)**: SV is predicted to delete the gene or truncate the gene product.
-2. ![](https://placehold.it/15/7459B2/000000?text=+) **Intragenic exonic duplication (IED)**: SV is predicted to result in duplicated exons within the gene, without extending beyond the boundaries of the open reading frame. (New in gnomAD v3)
-3. **Partial exon duplication (PED)**: SV is predicted to duplicate part of one or more exons without resulting in a whole-gene copy gain. (New in gnomAD v3)

 4. ![](https://placehold.it/15/2376B2/000000?text=+) **Copy gain (CG)**: SV is predicted to result in an entire additional intact copy of the gene.
 
 ### Other consequences
 
-4. **Transcription start site duplication**: SV is predicted to result in a duplication of a transcription start site but not result in any other, more severe consequences. (New in gnomAD v3).
+4. **Transcription start site duplication**: SV is predicted to result in a duplication of a transcription start site but not result in any other, more severe consequences. (New in gnomAD v4).
 5. **MCNV overlap**: MCNV overlaps one or more protein-coding exons; exact consequence depends on the number of copies and their orientation.
 
 6. **Partial duplication**: SV is predicted to partially duplicate the gene while leaving the original copy of the gene intact.
-7. **Exonic breakend**: breakend localizes to exonic locus, but consequence is unclear as SV is incompletely resolved. (New in gnomAD v3).
+7. **Exonic breakend**: breakend localizes to exonic locus, but consequence is unclear as SV is incompletely resolved. (New in gnomAD v4).
 8. **UTR**: SV does not directly disrupt coding sequence, but overlaps one of the gene's untranslated regions (UTRs).
 9. **Promoter**: SV does not directly disrupt coding sequence or promoter, but is within 2kb of the gene's transcription start site.
 10. **Inversion span**: gene is entirely spanned by an inversion SV without being directly disrupted.
