Whether deaf and dumb is a hereditary disease ?!


Question: Whether deaf and dumb is a hereditary disease ?
deaf and dumb disability by birth

Answers:

I myself am an E.N.T.Surgeon dealing with such cases daily.
The familial inheritance or children in families having deafness due to different congenital disorders is known.High incidence of such condition is there among children from consanguineous marriages or marriage among close relatives.
Recently in Radhoud medical school ,Nijmegen ,Netherlands research revealed a definite association of a gene they named PTPRQ gene with such incidence .Thus shortly it might be possible to foretell the occurrence of such condition by amniocentesis or taking out fluid from womb before the baby is born.
Till then counselling to prevent consanguineous marriages can be undertaken.But it would be inhuman to prevent deaf mutes from getting married but they do run a high risk of begetting deaf mutes.
