    Hereditary hearing impairment (HHI) is a common but heterogeneous clinical entity caused by mutations in a plethora of deafness genes. Research over the past few decades has shown that the genetic epidemiology of HHI varies significantly across populations. In this study, we used different genetic examination strategies to address the genetic causes of HHI in a large Taiwanese cohort . A hearing impairment can be caused by many physical conditions (for example, childhood illnesses, pregnancy-related illnesses, injury, heredity, age, excessive or prolonged exposure to noise), and result in varying degrees of hearing loss. Generally, hearing impairments are categorized as mild, moderate, severe, or profound.

This protocol primarily focuses on the use of genetic testing to identify a cause of suspected hereditary hearing loss. The diagnosis of syndromic hearing loss can be made on the basis of associated clinical findings. However.

Generally, the younger the person is with a hearing impairment, the more likely it was down to genetic factors, disease or physical abnormality. Genes can cause hearing loss in many different ways. Even if one’s hearing loss is down to old age though – genetic. Genetic factors contribute to 50% of deafness cases including syndromic (30%) and non–syndromic (70%) hearing impairment [1, 2].

Recent times have witnessed rapid progress in the field of genetic studies of hereditary hearing impairment, especially of non–syndromic hearing impairment. Hearing loss has many causes. 50% to 60% of hearing loss in babies is due to genetic causes.

There are also a number of things in the environment that can cause hearing loss. 25% or more of hearing loss in babies is due to “environmental” causes such as maternal infections during pregnancy and complications after birth.

"Hearing impairment" means an impairment in hearing, whether permanent or fluctuating, that adversely affects a child's educational performance but that is not included under the definition of deafness in this part. Audiological Indicators a. hearing impairment has been equated as 40% hearing impairment as in Persons with Disability (Full Participation, Equal Opportunity and Protection of Rights) Act, The definition of hearing disabled as stipulated in the PWD Act, is a person who has a minimum of 60dBHL of hearing impairment in the better ear in speech conversation.

In The Effects of Genetic Hearing Impairment in the Family, under the aegis of the European Union GENDEAF programme, the editors have taken the first steps to address this deficit in our knowledge and understanding of this topic.

The book addresses the problem by secondary analyses of existing large scale population studies, by prospective. From the National Center for Hearing Assessment and Management. This electronic “e-book” outlines some of the most important issues which need to be addressed in implementing and operating a successful early identification of hearing loss program for newborns.

Hearing impairments are classified in terms of the severity and type of hearing impairment. The severity of the hearing impairment is categorized based.

Most studies on genetic hearing loss have been done in mice. Work in large animal models such as pigs is ongoing, but work in non-human primates is needed.

To conduct clinical trials, it is essential to know the “natural history” of each genetic type of hearing loss, i.e., the onset of hearing loss, the severity and the progression over time.

The better ear hearing threshold level was defined as a pure-tone average of thresholds at1, 2 and 4 kHz. In accordance with the European Union recommendations, a person was defined as having hearing impairment if the hearing threshold level of the better ear was ≥21 dB.

Approximately % of hearing impairment is associated with genetic factors, and these cases are categorized as either syndromic hearing loss (SHL) or nonsyndromic hearing impairment (NSHI) []. Nonsyndromic hearing impairment can present at any age and can result from various inheritance patterns, including autosomal recessive, autosomal.
