The localisation of different genes for non-syndromic hearing impairment in close proximity is not surprising. Non-syndromic hearing impairment is the most genetically heterogeneous disease known. [jmg.bmj.com]

Autosomal dominant nonsyndromic hearing impairment The characteristic phenotype of a person with autosomal dominant nonsyndromic hearing impairment is a progressive postlingual hearing loss that begins in the second to third decades of life. [nature.com]

For example, scientists have identified the DFNA10 gene, which causes progressive hearing loss later in adulthood 3. [nationalhearingtest.org]

Among the heterozygous group, 66.6% demonstrated a slowly progressive hearing loss, while 100% of the homozygous group demonstrated a rapidly progressing hearing loss (table 1 ). [karger.com]

His mother also carried the mutation but had normal hearing. Consequently, the mutation was not considered to be the cause of the proband's hearing loss. [ncbi.nlm.nih.gov]

This variation was not found in the 100 unrelated individuals with normal hearing (data not shown). [bmcmedgenet.biomedcentral.com]

A child born with hearing loss of a genetic nature can have parents with normal hearing. Quite often parents are carriers of a genetic disorder and yet do not display that disorder themselves. [nationalhearingtest.org]

Sibs of a proband At conception, each sib has a 25% chance of being deaf, a 50% chance of having normal hearing and being a carrier, and a 25% chance of having normal hearing and not being a carrier. [consilieregenetica.org]

Postlingual hearing loss occurs after the development of normal speech. Severity Hearing is measured in decibels (dB). [nature.com]

The presence of postlingual hearing loss cases in the present study could be due to apparent identification by the patient's parent that their child suffers from hearing loss. [karger.com]

Reevaluation of this survey of 1851 confirms sex linked deafness as a factor in the disproportionate number of deaf males and suggests that 5% of congenital male deafness was the result of sex linked recessive deafness. [semanticscholar.org]

When compared longitudinally, however, the concentrations of CSF biomarkers of neuronal injury/death within individuals decreased after their EAO, suggesting a slowing of acute neurodegenerative processes with symptomatic disease progression. [stm.sciencemag.org]

The inner ear processes sound and sends the information to the brain in the form of electrical nerve impulses. Less commonly, nonsyndromic hearing loss is described as conductive, meaning it results from changes in the middle ear. [ghr.nlm.nih.gov]
