Service Description

This test uses PCR-Sequencing to check for genetic variation in the GJB2 gene that can cause hearing loss in both ears. The GJB2 gene provides instructions for making a protein called connexin 26, which is involved in the formation of gap junctions - channels that allow ions and small molecules to pass between neighbouring cells in the inner ear. The genetic variation in the GJB2 gene associated with bilateral hearing loss is caused by mutations that affect the function of the connexin 26 protein, leading to abnormal development or degeneration of the inner ear and resulting in hearing loss. The severity of hearing loss associated with this genetic variation can vary widely, ranging from mild to profound. Testing for the GJB2 gene mutations may be recommended for individuals with a personal or family history of hearing loss, or for individuals who are at increased risk due to other factors, such as exposure to loud noise or certain medications. However, it is important to note that genetic testing for Connexin 26 alone is not sufficient to predict an individual's risk of developing hearing loss, as many other factors, including environmental and lifestyle factors, also play a role. Therefore, genetic testing is typically only one part of an overall assessment of an individual's risk for hearing loss.
