Serum Clara cell protein (CC16): a new valid marker of the distal airway damages caused by air pollutants in rats

Two brothers, 17 and 21 years of age, with depressed nasal bridge, prominent frontal bones, hypoplastic maxilla, mild sensorineural hearing loss, broad terminal phalanges and mild pulmonary stenosis are presented. These findings are similar to those of the syndrome described by Keipert et al. in 1973. To the best of our knowledge, this is only the second report of this syndrome.
