Congenital hearing loss is a hearing loss present at birth. It can include hereditary hearing loss or hearing loss due to other factors present either in-utero (prenatal) or at the time of birth. It can include hereditary hearing loss or hearing loss due to other factors present either in-utero (prenatal) or at the time of birth.
Hearing loss can be inherited. Around 75–80% of all these cases are inherited by recessive genes , 20–25% are inherited by dominant genes , 1–2% are inherited by X-linked patterns, and fewer than 1% are inherited by mitochondrial inheritance .

Gene therapy has allowed several children born with inherited deafness to hear. On Tuesday, the Children's Hospital of Philadelphia announced similar improvements in an 11-year-old boy treated there.
The experimental therapy focuses on hereditary deafness and one rare condition only. Genes are responsible for as much as 60% […] The post Philadelphia child, 11, hears for first time ever after ...
Genetic testing: Genetic testing may be recommended, especially if there is a family history of hearing loss. Nonsyndromic deafness can be caused by mutations in various genes associated with auditory function.
Prelingual hearing loss can be considered congenital, present at birth, or acquired, occurring after birth before the age of one. Congenital hearing loss can be a result of maternal factors (rubella, cytomegalovirus, or herpes simplex virus, syphilis, diabetes), infections, toxicity (pharmaceutical drugs, alcohol, other drugs), asphyxia, trauma, low birth weight, prematurity, jaundice, and ...
Tietz syndrome is caused by mutations in the MITF gene, located on human chromosome 3p14.1-p12.3. [2] [4] [7] It is inherited in an autosomal dominant manner. [2]This indicates that the defective gene responsible for a disorder is located on an autosome (chromosome 3 is an autosome), and only one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who ...
