+The tables below allow sorting and filtering.
+
+**Sorting** - Click any column header to sort ascending or descending.
+
+**Filtering** - Use the boxes at the top of each column to filter results. The tables support **regular expression (regex)** search:
+
+  - Exact match (recommended for genes): `^TP53$` → matches only TP53
+  - Starts with: `^BRCA`
+  - Ends with: `TP53$`
