More than 360 million humans are affected with some degree of hearing loss, either early or later in life. A genetic cause for the disorder is present in a majority of the cases. We mapped a locus (DFNB101) for hearing loss in humans to chromosome 5q in a consanguineous Pakistani family. Exome sequencing revealed an insertion mutation in GRXCR2 as the cause of moderate‐to‐severe and likely progressive hearing loss in the affected individuals of the family. The frameshift mutation is predicted… 
Identification of OSBPL2 as a novel candidate gene for progressive nonsyndromic hearing loss by whole-exome sequencing
This study is the first to implicate OSBPL2 mutations in autosomal dominant nonsyndromic hearing loss and modeling and structure-based analysis support the theory that this gene deletion is functionally deleterious.
EPS8L2 is a new causal gene for childhood onset autosomal recessive progressive hearing loss
Whole-exome sequencing allowed us to identify a new gene responsible for childhood progressive hearing loss transmitted on the autosomal recessive mode, and it was identified in EPS8L2, encoding Epidermal growth factor receptor Pathway Substrate 8 L 2, a protein of hair cells’ stereocilia previously implicated in progressive deafness in the mouse.
Identification of Two Novel Compound Heterozygous PTPRQ Mutations Associated with Autosomal Recessive Hearing Loss in a Chinese Family
Mutations in PTPRQ are associated with deafness in humans due to defects of stereocilia in hair cells. Using whole exome sequencing, we identified responsible gene of family 1572 with autosomal
Genetics of Nonsyndromic Congenital Hearing Loss
An overview of the currently known genes associated with nonsyndromic congenital hearing loss and mutations in the inner ear is presented.
Genetic causes of moderate to severe hearing loss point to modifiers
The genetic underpinnings of recessively inherited moderate to severe sensorineural hearing loss are not well understood, despite its higher prevalence in comparison to profound deafness, and data point to a prominent role for genetic background, environmental factors or both as modifiers of human hearing loss severity.

Genetic Predisposition to Sporadic Congenital Hearing Loss in a Pediatric Population
Genetic inheritance in simplex cases of severe-to-profound congenital hearing loss in Korean children found to mostly exhibit an autosomal recessive inheritance pattern is delineated.
Impact of next-generation sequencing on molecular diagnosis of inherited non-syndromic hearing loss
This review describes major NGS methodologies currently used for genetic disorders and highlights applications of these technologies in studies of molecular diagnosis and the discovery of genes implicated in non-syndromic hearing loss.
Genetic Elucidation of Nonsyndromic Hearing Loss in the High-Throughput Sequencing Era
Progress in the field of molecular genetics has never occurred at such a remarkable pace or been at such an exciting crossroad for expedited identification of the genes involved in hearing loss.


Homozygosity mapping reveals mutations of GRXCR1 as a cause of autosomal-recessive nonsyndromic hearing impairment.
Mutations in Grxcr1 are the basis for inner ear dysfunction in the pirouette mouse.
Linkage Study and Exome Sequencing Identify a BDP1 Mutation Associated with Hereditary Hearing Loss
The identification of the BDP1 mutation increases the knowledge of the molecular bases of Nonsyndromic Hereditary Hearing Loss and provides new opportunities for the diagnosis and treatment of this disease in the Qatari population.
Mutations of the gene encoding otogelin are a cause of autosomal-recessive nonsyndromic moderate hearing impairment.
The LINC complex is essential for hearing.
It is demonstrated that the LINC complex is essential for viability and normal morphology of OHCs and suggested that the position of the nucleus in sensory epithelial cells is critical for maintenance of normal hearing.
Destabilization and Mislocalization of POU3F4 by C‐Terminal Frameshift Truncation and Extension Mutation
It is concluded that frameshift truncation and extension mutations in the C‐terminus of POU3F4 lead to cytoplasmic localization and subsequent proteosomal degradation due to structural aberrations, which cause transcriptional inactivity and thus nonsyndromic hearing loss.
A mutation in CABP2, expressed in cochlear hair cells, causes autosomal-recessive hearing impairment.
Dominant modifier DFNM1 suppresses recessive deafness DFNB26
A new recessive nonsyndromic deafness locus is mapped to a 1.5-cM interval of chromosome 4q31 in a consanguineous Pakistani family and seven unaffected family members who are also homozygous for the DFNB26-linked haplotype and thus are non-penetrant are mapped.
A Rapid and Cost-Effective Protocol for Screening Known Genes for Autosomal Recessive Deafness.
A protocol to reduce the time and costs of microsatellite based screening for deafness by selecting micros satellite markers close to the known deafness genes thereby decreasing the number of markers required to screen for each locus and multiplexing the PCR reactions.
KinSNP software for homozygosity mapping of disease genes using SNP microarrays
KinSNP, a user-friendly software tool for homozygosity mapping using SNP arrays, is presented and the software has been used to identify the location of a mutated gene causing insensitivity to pain in a large Bedouin family.
