Hearing loss represents the most common sensory disability of children. Remarkable advances in the identification of genes underlying nonsyndromic and syndromic hearing loss in just the last 2 decades have led to the ability to determine the specific genetic cause of hearing loss in many children. Surprisingly one gene, GJB2, encoding the protein connexin-26, accounts for about 20 % of sensorineural hearing loss (including in India) and is considered the first tier test in evaluating an infant… 
Moderate-Severe Hearing Loss in Children: A Diagnostic and Rehabilitative Challenge.
The audiological follow-up of those affected by moderate-severe hearing loss must be tight, as it is necessary to verify constantly: hearing threshold levels, adequateness of hearing aids fitting, and language development.
Evaluation and management of syndromic congenital hearing loss
A significant portion of childhood hearing loss is associated with a syndrome and surgical intervention including a bone-anchored hearing aid or cochlear implant or targeted gene therapies may become a viable option for treating syndromic hearing loss.

Editorial: New Horizons in Genetic Diagnosis in Pediatric Practice: The Excitement and Challenges!
A minimum basic genetic knowledge is required for all clinicians, especially pediatricians, in whose ambit many genetic diagnostic challenges lie, and it may be difficult at times to decide that which is the most appropriate test in a particular clinical setting.
A Study of JCIH (Joint Commission on Infant Hearing) Risk Factors for Hearing Loss in Babies of NICU and Well Baby Nursery at a Tertiary Care Center
Data analysis revealed that family history of deafness, anemia and hypertension in ANC, TORCH in mother, low Apgar score and hyperbillirubinemia in newborns were a major risk factor for hearing impairment.

Early screening, early diagnosis, and early intervention services by 6 months of age are necessary to optimize the language outcomes of preterm infants with permanent hearing loss.


American College of Medical Genetics and Genomics guideline for the clinical evaluation and etiologic diagnosis of hearing loss
This guideline offers information about the frequency, causes, and presentations of hearing loss and suggests approaches to the clinical evaluation of deaf and hard-of-hearing individuals aimed at identifying an etiologic diagnosis and providing informative and effective patient education and genetic counseling.
Frequency of Usher syndrome in two pediatric populations: Implications for genetic screening of deaf and hard of hearing children
The results demonstrate that DNA testing for Usher syndrome is feasible and may be a useful addition to newborn hearing screening programs.
Methodology of a multistate study of congenital hearing loss: Preliminary data from Utah newborn screening
This is the first comprehensive investigation to determine the etiology of hearing loss from populations ascertained through E HDI programs, and the results of this study will facilitate the incorporation of genetic services into EHDI programs.
Low prevalence of GJB2 mutations in non-syndromic hearing loss in Western India
Cx30 mutations do not contribute to the autosomal recessive non-syndromic hearing loss (NSHL) in the Indian population, implying the need to explore other contributory loci.

A brief history of Robert J. Gorlin's research into genetic hearing loss and its role in syndrome delineation and heteroegeneity and hearing loss - epidemiology, etiology, and genetic patterns.
Newborn hearing screening--a silent revolution.
The implementation of universal screening programs to detect hearing defects in newborns has dramatically increased the identification of hearing loss in infants, and further improvement in these programs can readily be achieved.

A diagnostic paradigm including cytomegalovirus testing for idiopathic pediatric sensorineural hearing loss
To determine the feasibility and cost effectiveness of incorporating cytomegalovirus (CMV) testing to determine the etiology of pediatric hearing loss, a large number of studies have found it to be cost-effective.
