Connexin 30 (GJB6) DNA Test
Also known as: CX30, gap junction protein, beta-6
Use
This test evaluates the common 342 kb deletion in the GJB6 (Connexin 30) gene, which is implicated in hereditary hearing loss. It is particularly useful for identifying a second mutation in patients already carrying a single GJB2 (Connexin 26) mutation, determining the genetic basis for hearing loss in affected individuals, and supporting prenatal diagnosis in at-risk families.
Special Instructions

Limitations
The test detects only the common 342 kb deletion in GJB6. Mutations other than this deletion will not be identified.
