Cystic fibrosis mutations R1162X and 2183AA<FONT FACE=Symbol>&reg;</FONT>G in two southern Brasilian states

We screened 79 southern Brazilian patients with cystic fibrosis for the rare cystic fibrosis mutations R1162X and 2183AA<FONT FACE="Symbol">&reg;</FONT>G. Forty-nine patients were born in the State of Paraná (PR) and 30 in the State of Santa Catarina (SC). Two 2183AA<FON...
