140 Three novel missense mutations (E1401K, P439S, and V1108L), not detected in the general population or in patients with CF, were here first described in patients with CAVD. Login to comment
141 Although the pathogenicity of these mutations is still being assessed by expression and functional in vitro studies, the combination of the amino acid substitutions with other mutations (deltaF508/E1401K, R334W/P439S, V1108L/T5) might be responsible for the CBAVD phenotype. Login to comment
