NOVELTY – A genetic deafness test technique using cellulose paper to collect biological material for analysis, based on nucleic acid bonding, and using an amplification reaction needing only a 1-3mm droplet of peripheral blood, is new. USE – The technique detects carriers of mutation 35de1G in the conessine-26 gene, to diagnose genetic deafness.
