Expanded Hearing Loss Panel, Sequencing and Deletion/Duplication
Copy Utility
Most comprehensive genetic test for nonsyndromic and syndromic hearing loss. Recommended test for nonsyndromic hearing loss if GJB2, GJB6, and mitochondrial variant testing is negative. Recommended test for syndromic hearing loss if symptoms are consistent with disorders included on the panel.
