Case presentation A neutered male white domestic short hair cat under-went BAER test at 8months of age that revealed pro-found deafness of the left ear and the presence of the ASNR. 1.. IntroductionA vertex-negative potential with a latency of 3 ms was observed in response to loud sound stimuli in brain stem auditory evoked potential (BAEP) waveforms of some human patients with profound deafness of cochlear origin (Kato et al., 1998, Nong et al., 2000).This deflection was termed the N3 potential and was supposed to be a vestibular evoked potential to acoustic stimulation. Causes: Deafness can be either inherited or acquired. Shin Kariya, Sebahattin Cureoglu, Patricia A. Schachern, Andre L.L. Communication Center for the Deaf and Hard of Hearing, Inc. of Central Florida is a non-profit, community organization whose pursuit is to serve the members of the Deaf and Hard of Hearing communities in Osceola County and the surrounding Central Florida area. This mutation was caused by the insertion of a transgene into distal chromosome 7 affecting expression of native genes. It is usually seen in dogs with the piebald color genes or merle color gene. The merle gene causes white pigment and has been associated . Overview. 37 Full PDFs related to this paper. These vertexnegative potentials have been identified in human patients with neuroepithelial deafness and in animals with suspected cochleosaccular deafness. 221400 - DEAFNESS, NERVE TYPE, WITH MESENTERIC DIVERTICULA OF SMALL BOWEL AND PROGRESSIVE SENSORY NEUROPATHY - GROLL-HIRSCHOWITZ SYNDROME .

Cochleosaccular deafness in dogs is usually seen with the piebald or merle genes and in cats with white coat color. It is usually seen in dogs with the piebald color genes or merle . Type of disease: Rare conditions.
There has been no quantitative study on the peripheral vestibular system in cochleosaccular dysplasia. Abnormalities of the middle ear ossicles or ligaments, which can be associated with anomalies of the first and second arches, can interfere with transmission, resulting in middle ear deafness. Causes: Deafness can be either inherited or acquired. Hereditary deafness can be either cochleosaccular or neuroepithelial in origin. To investigate quantitatively the extent of pathologic changes of the vestibular sensory epithelium in .
PubMed is a searchable database of medical literature and lists journal articles that discuss Cochleosaccular degeneration of the inner ear and progressive cataracts. Conditions such as rubella can lead to maldevelopment of the organ of Corti that causes inner ear deafness. CONCLUSIONS: GJB2 mutations can cause deafness in KID syndrome, and possibly in other GJB2 mutant phenotypes, by disrupting cochlear differentiation. Cochleosaccular is a type that is generally linked to pigment genes in their coats and blue eyes. These results confirm that a saccular origin for the ASNR in this case, and in general in cats and dogs with congenital deafness associated with white pigmentation, is . Hereditary deafness, also known as loss of hearing at birth, might occur in Frenchies with white coat pigmentation. cochleosaccular degeneration. However, cochleosaccular defect is rarely associated with non-syndromic hearing loss. A new syndrome of cataracts and progressive sensorineural hearing loss, inherited as an autosomal dominant trait, is described. Patients with WS may also experience primary vestibular symptoms. Hereditary deafness can be of either cochleosaccular or neuroepithelial origin. (1997), with deafness caused by cochleosaccular degeneration (CSD).CSD is the most common histopathologic finding in cases of profound congenital deafness and is estimated to occur in approximately 70% of cases.

Division of Community Health Promotion. Neuroepithelial Deafness - This type of congenital deafness occurs in newborn puppies regardless of coat patterns. A familial history of deafness was found in three cases. It's most common in dogs with piebald or Merle color genes. The variation, perhaps, reflects the different etiologies involved in the origin of cochleosaccular dysplasia. Study design: This human temporal bone histopathologic study of a series of deaf-mute cases involves morphometric analysis, including stria vascularis and spiral ligament area measurements and .

We also discuss the possible sense organ and generator in-volved in the ASNR and VEMP generation. The disorder should be called cochleosaccular . The type of hearing loss is sensorineural and is due to the breakdown . It causes deafness in one or both ears and is frequently accompanied by blue eyes and white pigmentation. Cochleosaccular dysplasia is the most common pathologic finding seen in children with profound congenital sensorineural hearing loss. People with this disorder have progressive hearing loss as well as progressive cataracts. Conclusions: This case report describes the auditory and histopathologic findings of a cat that showed an ASNR during BAER test despite the presence of cochleosaccular deafness.
It produces deafness in one or both ears and is often associated with blue eyes and white pigmentation. Both ears are usually affected and are typically detected at the same age as cochleosaccular deafness.
3. In congenital cochleosaccular deafness, strial degeneration is associated with the absence of pigment producing cells or melanocytes . Why are white dogs deaf? It is usually seen in dogs with the piebald color genes or merle color gene. Read More . The variation, perhaps, reflects the different etiologies involved in the origin of cochleosaccular dysplasia. It is usually seen in dogs with the Pied or Merle color genes. One of these genes is GJB2, encoding connexin 26, a polypeptide component of . Description of cochleosaccular dysplasia of the inner ear in congenitally deaf patients is attributed to Scheibe (1892). ORL 43: 4 . INTRODUCTION. Cochleosaccular Deafness - This is the most common cause of congenital deafness in dogs and is linked with hair coat color patterns. MOLECULAR BASIS - Caused by mutation in the myosin, heavy chain 9, nonmuscle gene (MYH9, 160775.0008) Creation Date: Cochleosaccular degeneration-cataract syndrome is characterised by progressive sensorineural hearing loss due to severe cochleosaccular degeneration and cataract. 8 , 9 This defect mimics the Scheibe deformity of the human cochlea that produces deafness primarily or in association with Waardenburg's 10 and other 11 syndromic forms of deafness. INTRODUCTION. There are hundreds of genes in which mutations cause sensorineural hearing loss (SNHL) either alone or in combination with other abnormalities as part of a syndrome. Thank you for visiting the new GARD website. The hereditary deafness can be classified as cochleosaccular, neuroepithelial, or congenital in origin. There are hundreds of genes in which mutations cause sensorineural hearing loss (SNHL) either alone or in combination with other abnormalities as part of a syndrome. Cochleosaccular deafness is more common in dogs with the piebald or merle genes and cats with white coats.

The deafness phenotype was mapped to CFA10 (maximum linkage peak on CFA10 log10 p-value = 3.64), as was both coat colour and speckling. (Aaron, 2022) Congenital deafness can have two origins: neuroepithelial or cochleosaccular. Objective: The objective of this study was to perform a morphometric analysis of a series of temporal bones with cochleosaccular dysplasia to clarify the extent of inner ear changes in this disease.
