Protein is one kind of organic molecule.  It’s main function is to build the structure of the body.  These are examples of proteins:

This structure is responsible for balance and coordination.  

Auditory Neuropathy Spectrum Disorders, a range of neural-based hearing issues, are characterized by which of the following? (Choose all that apply)

True/False: In this case, TEOAE findings provided an accurate assessment of outer hair cell function. 

Mutation of the GJB2 gene is a common form of non-syndromic hearing loss, which affects Connexin 26 protein formation. Changes in this protein formation can cause hearing loss in which part of the ear? 

Use Tympanogram #1 and Table 1 to answer the following:   True/False: Results in Tympanogram #1 are consistent with middle ear effusion.

Which of the following are considered the main skill set(s) for auditory processing? (Choose all that apply)

True/False: Results from frequency-specific ABR testing using tone bursts are closely correlated with pure tone behavioral hearing testing. 

Case Study #1   Below, you see the test findings for a comprehensive audiometric evaluation including TEOAEs and tympanometry. The patient was a compliant 5 year old and you felt confident that the findings are accurate. Tympanometric, TEOAE, and acoustic reflex testing results were identical for the left and right ears. TEOAEs resulted in a REFER (in both ears). Acoustic reflex thresholds were absent (no response) in both ears for all test frequencies. Use this information and Table 1. (tympanometric norms) to answer the following questions.    

Which genetic disorder leads to progressive hearing loss and end stage renal disease?
