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.
Massively Parallel Sequencing/Exonic Oligonucleotide-based CGH Microarray
Lavender (EDTA) or yellow (ACD Solution A or B). Peripheral blood required.
Transport 3 mL whole blood. (Min: 1 mL)
