Comment | The mutation A-G at position 1453 was found in two unrelated individuals (Hyd-1 and Hyd-2) showed typical maternal inheritance segregating in three generations.The sample Hyd-1 also showed homozygosity for W24X mutation in Exon-2 of GJB2 gene. The proband had severe hearing impairment requiring 110 decibels. This probably indicates the interaction of nuclear-mitochondrial genes influencing clinical expression.%%The sample Hyd-2 did not show mutations %screened in GJB2 (35delG, W24X, 231G-A, 235delC, 167delT in Exon-2 of Connexin 26) and GJB6 (342Kb deletion in Exon-3 of Connexin 30).%%Entire GJB6 gene was screened for possible mutations by SSCP but no variation was found in the two DNA samples reported. |
