+### Condensed summary stats for one or more samples over a list of HGNC IDs
+
+To obtain condensed statistics for one or more samples, use the `/coverage/d4/genes/summary` endpoint. 
+Send a request with a list of HGNC gene IDs, the path to the d4 files for the samples, and the coverage threshold for computing coverage completeness. 
+The endpoint will return the average coverage and coverage completeness for all the genes included in the query.
+You need to provide a parameter `interval_type` to specify whether the statistics should be computed over entire genes, gene transcripts, or exons.
