Description

Phe83Leu in exon 2 of GJB2: This variant is not expected to have clinical signif icance because it has been identified in 0.3% (28/8572) of European American chr omosomes and 0.07% (3/4403) of African American chromosomes from a broad populat ion by the NHLBI Exome sequencing project (http://evs.gs.washington.edu/EVS/; db SNP rs111033218). In addition, this has been observed at equal frequencies in af fected individuals and controls (Scott 1998, Heathcote 2000, Prasad 2000, Rabion et 2000, Pandya 2003, Bruzzone 2003, Frei 2004, Roux 2004, Sinnathuray 2004, Che ng 2005, Santos 2005, Frei 2006, Tang 2006, Ramsebner 2007, Ross 2007, Picotti 2 009, Lee 2009, Kimani 2010). Furthermore, functional studies revealed that the v ariant protein behaves similar to that of the wild type protein (Bruzzone 2003).
