What can cause a baby to be born deaf?
Infections such as rubella, cytomegalovirus (CMV), toxoplasmosis and herpes can cause a child to be born deaf. There are also a range of medicines, known as ototoxic drugs, which can damage a baby’s hearing system before birth.
Is being born deaf hereditary?
Deafness can be an inherited condition that is present when a baby is born. Inherited deafness can also develop over time during childhood or adulthood. According to the American Hearing Research Foundation, about 1 out of every 1,000 to 2,000 births involves congenital deafness.
What happens if a baby is born deaf?
The birth of a deaf child changes their world. Parents often experience the gamut of possible responses-from overprotection to rejection. They may feel that they have produced a child who is genetically inferior and that they need to work arduously as the child’s advocate to mitigate the perceived impairment.
What percentage of deafness is genetic?
Hearing loss has many causes. 50% to 60% of hearing loss in babies is due to genetic causes. There are also a number of things in the environment that can cause hearing loss.
Do deaf babies cry?
Mean duration of cries in the deaf group was 0.5845 ± 0.6150 s (range 0.08-5.2 s), while in the group of normal hearing cases was 0.5387 ± 0.2631 (range 0.06-1.75 s). From the deaf group, five cases had very prolonged duration of cries, without statistical significance.
Are deaf babies quiet?

Can two genetically deaf parents have a hearing child?
Nearly 25% of the genes in the human genome are likely to be involved in hearing since they are expressed in the developing human cochlea. Two deaf parents with unknown genetic information have a 10% chance of having a deaf child.
Is deaf and dumb genetic?
An analysis of 240 deaf-mute students revealed that the main cause of congenital deafness had been heredity (68.5%) which was different from that before 1970s. Of the patients with delayed deafness, 29.8% were hereditary.

Can deaf be cured?
There is currently no cure for sensorineural hearing loss, and the best treatment option is to improve your hearing by wearing hearing aids.
What is the most common gene responsible for deafness?
The most common cause of moderate autosomal recessive nonsyndromic hearing loss is mutations in the STRC gene. These mutations cause a form of the condition known as DFNB16. Mutations in more than 60 other genes can also cause autosomal recessive nonsyndromic hearing loss.
