Nonsyndromic X-linked hearing loss.
To date, 135 loci and 50 genes have been identified as causes of nonsyndromic hearing loss. Until recently, four loci (DFN2, DFN3, DFN4, and DFN6) had been implicated in nonsyndromic X-linked hearing loss; however, a new classification (DFNX1-5) has been proposed to reduce confusion in the terminology. The different types of nonsyndromic X-linked hearing loss demonstrate various clinical featur...
متن کاملGenetics Evaluation Guidelines for the Etiologic Diagnosis of Congenital Hearing Loss Genetic Evaluation of Congenital Hearing Loss Expert Panel
The advent of hearing screening in newborns in many states has led to an increase in the use of genetic testing and related genetic services in the follow-up of infants with hearing loss. A significant proportion of those with congenital hearing loss have genetic etiologies underlying their hearing loss. To ensure that those identified with congenital hearing loss receive the genetic services a...
متن کاملGenetics of Hearing Loss
The revolution in genetics in the past decades has enabled identification of many of the genes associated with human hereditary diseases, and hearing loss is no exception. These discoveries have a profound impact on knowledge about inner ear function and the pathology caused by mutations in these genes, which becomes clinically and socially relevant because a significant proportion of hearing l...
متن کاملHearing loss: A review on molecular genetics and epidemiologic aspects
Background and aims: Hearing loss (HL) happens due to the genetic or environmental causes or both. Risk factors include congenital infections and congenital deformities of auricle and ear duct. The present study was performed to briefly explain the genetics, molecular biology and epidemiology of HL in Middle East especially in Iran. Methods: An intense an...
متن کاملPresymptomatic diagnosis of nonsyndromic hearing loss by genotyping.
BACKGROUND Nonsyndromic hearing loss (NSHL) is the most common type of hereditary hearing impairment (HHI). It is genetically heterogeneous, and although the exact number of genes is not known, 38 loci have been identified. By cloning the relevant genes and studying the function of the encoded proteins at the molecular level, it may be possible to impact the habitation of persons at risk for HH...
