+title: Proportion expressed across transcripts (pext) on gnomAD v4.1
+date: "2024-11-22"
+order: 1
+---
+
+Updated transcript tissue expression and proportion expressed across transcripts (pext) tracks have been added to the gene pages in the gnomAD v4 browser.
+
+<!-- end_excerpt -->
+
+The updated tracks in the gnomAD v4 browser were generated using [GTEx v10](https://gtexportal.org/home/home/news?id=530) bulk tissue transcript expression [data](https://gtexportal.org/home/downloads/adult-gtex/bulk_tissue_expression).

+
+The previous versions of these tracks, available in the gnomAD v2 browser, were generated using [GTEx v7](https://gtexportal.org/home/downloads/adult-gtex/bulk_tissue_expression). For more information about the proportion expressed across transcripts (pext) score, including its utility and how it is generated, please see our [help page](https://gnomad.broadinstitute.org/help/pext).
