How is the Connexin 26 gene (causes deafness) passed down from generations?
Kiliana’s Mommy asked:
My daughter was diagnosed with profound sensorineural hearing loss caused by the mutated gene Connexin 26. I know how she got the gene (me and her father both have a copy of the gene and passed it down to her); but I am wondering how we, the parents, got the gene. Do both of our parents have to have it to pass it down? Who else in our family may have a copy of this gene?
Advice on the best software

GJB2 gene or commonlycalled connexin 26 is inherited in autosomal recessive pattern.. that is both parents need to be carrying A defective gene in order the child be born deaf….
in your case, both u and child father are carriers. And each of you must have received the defective gene from one of your parent, ( who would also be carriers ) and the other parent most likely be neither a carrier or a deaf person..
