According to the US Centers for Disease Control and Prevention (CDC) definition, genetic counseling is a process in which information is presented about how genetic conditions affect a patient or his/her family. A genetic counselor collects a patient’s personal and family health history to promote the family’s awareness and perception of specific genetic diseases, testing risks and advantages, disease management, and assessment of available therapeutic options. Intellectual disability (ID) and deafness are two common disabilities with considerable impacts on the quality of life of patients and their families. The present research has investigated the role of genetic counseling in the screening and prevention of deafness and ID based on the studies published in the Web of Science, PubMed, and Google Scholar databases between 2015 and 2023. Genetic counseling can be employed as an influential tool in screening, early diagnosis, and prevention of ID and deafness. Considering that many cases of ID and deafness are rooted in individual genetics, genetic counseling can help lessen the risk factors of developing these disabilities and improve the quality of individual and family life. The effect of genetic counseling, as an influential tool, on screening, early diagnosis, and prevention of ID and hearing loss is also assessed.
