Genetic Knowledge among Audiologist Related to Hearing Loss – Recently Published article

Recently Journal of phonetics and Audiology Released first issue in which first article published was a research article entitled “Genetic Knowledge among Audiologist Related to Hearing Loss

Hearing loss is the loss of hearing which may be due to tumors, trauma, genetic factors, aging etc. The main aim and objective of the study is experimental studies conducted regarding knowledge about hearing loss related to genetics, involving 100 participants out of which 31 responded. 25 questions were validated and send through e-mails, responses from all the active participants were analysed. Findings have implicated that the audiologist have sufficient knowledge but practical skills are insufficient and there is a need to know about genetics of hearing loss. Knowledge about this increases self-confidence, better planning and treatment, better understanding of genetic disorders related to audiology

Hearing loss is relatively common in the human population. Profound congenital hearing loss is estimated to occur in about 1 in 1000 births [1,2]. Early intervention has been shown to be effective in facilitating speech and language development in deaf and hard-of-hearing children [3,4]. Ninety-five percent of newborns with hearing loss identified by newborn hearing screening programs are born to hearing parents, obscuring the fact that the majority of newborns have a hereditary cause for their hearing loss. The majority of genetic hearing loss is inherited in an autosomal recessive pattern and often presents in the absence of a positive family history for hearing loss [5]. One gene, GJB2, which encodes the gap junction protein connexin 26, accounts for the largest proportion of autosomal recessive early childhood hearing loss in many populations [6-9]. If a specific etiology is known, descriptions of hearing loss may also include the etiologic diagnosis, such as Usher syndrome type 1–related hearing loss or GJB2-related hearing loss.
