Abstract

Purpose:
The purpose of this study is to examine the studies of candidate genes in auditory processing disorder and studies of the effect of auditory deprivation in the critical period on the expression of genes and protein molecules and to determine the type and location of damage and the nature of auditory processing disorder.
Method:
In this review article, the words "genes and auditory processing disorder" and "auditory deprivation and auditory processing disorder" had searched in "Google Scholar" and "Science Direct"," pubmed ,"web of science" databases in the years 2000 to 2023.
Results:
After searching in Google Scholar and Science Direct and pubmed and web of science databases, 16 related and new articles were found and investigated.
Conclusion:
α2δ3 protein and kcna1 and pax6 genes are known as samples effective molecules in auditory processing disorder. Auditory deprivation in the critical period by changing the expression of GABA and glutamate receptor genes causes defects in hearing behaviors without affecting hearing thresholds. Identifying proteins and molecules effective in auditory processing disorder can be a way to diagnose auditory processing disorder.
