Do HUD/FHA 221(d)(4) loans qualify for Ginnie Mae securities?

The Government National Mortgage Association, otherwise known as Ginnie Mae, issues mortgage-backed securities, which are "backed by the full credit and faith of the U.S. government." These are based on FHA loans, which include HUD/FHA 221(d)(4) loans, as well as loans issued by the Department of Veterans Affairs (VA).
