It is likely that the condition is underdiagnosed, because males without an affected sister will likely be misdiagnosed as having isolated (nonsyndromic) hearing loss rather than Perrault syndrome. Find information on Genetic Disorders. Pendred syndrome is the most common form of syndromic hereditary SNHL. Hypertrophic cardiomyopathy with conduction defects, arrhythmias and late congestive heart failure shorten the life expectancy to 40-50 years of age. Patients with Jervell and Lange-Nielsen syndrome have a more severe cardiac phenotype than those with Romano-Ward syndrome. A much more rare mild/juvenile form of CD also exists that is characterized by mild developmental delay that may go unrecognized. 3) Congenital: hypotonia and generalized weakness at birth, often with respiratory insufficiency and early death, MR is common.

Common features include congenital sensorineural deafness; pale blue eyes, different colored eyes, or two colors within one eye; a white forelock . Although deafness is generally profound, it is variable and sometimes late in . Vision and Hearing. It is estimated to occur in 1/20,000 births. The signs and symptoms of this disorder vary considerably, even within the same family. Waardenburg syndrome is a genetic disorder that may be evident at birth (congenital). Pendred syndrome is autosomal recessive disorder characterized by congenital nerve . In addition to hearing loss, it is typically associated with a thyroid condition called a goiter. In total 28 patients who were diagnosed with Pendred syndrome received a cochear implant, 21 children and 7 adults. The majority of affected children have mutations in a gene called SLC26A4 on chromosome 7q31. . Children may be fitted for hearing aids early in life. It is important to note that Mosaic Down syndrome is not a fatal disorder, but the medical complications left untreated can prove to be fatal. Other Specialties.

Life expectancy is two to three years. 15% are autosomal dominant, while x-linked and mitochondrial . Treatment: Treatment for Pendred syndrome is focused on addressing hearing loss. However, many researchers estimate that it accounts for seven (7) to eight (8) percent of all hearing loss that is present from birth (congenital hearing loss). Type II can be subdivided into the late-infantile (onset age 1-3 years) and juvenile (onset age 3-10 years) phenotypes. Early Childhood.

Perrault syndrome is a rare disorder; fewer than 100 affected individuals have been described in the medical literature. The Center's carrier screening program currently screens for 260 recessive conditions, including about 50 conditions that occur more frequently among Ashkenazi Jews and Sephardic Jews. Pendred's syndrome is a major cause of congenital deafness. The thyroid is a gland responsible for normal body growth and metabolism. Pendred Syndrome does not affect the life expectancy of a child in any way, hence the prognosis of Pendred Syndrome is good. Quality of life was measured with the Nijmegen Cochlear Implant Questionnaire to evaluate the differences between pre- and post-implantation. Pendred syndrome; and other forms of dystonia or rarely Friedreich ataxia. The encoded protein, named pendrin, is closely related to numerous known proteins from a large taxonomic span, including plants, yeast, and bacteria . Life expectancy beyond 30 is unknown. Does life insurance cost more for the hearing impaired?. Most often caused by mutations in the SLC26A4 gene, the lack of production of pendrin protein distinguishes this rare thyroid disease.
