Detection of a de novo R1066H mutation in an Italian patient affected by cystic fibrosis.
Search for mutations in a cystic fibrosis patient, compound heterozygous for 1717-1G-->A and another uncharacterized molecular defect, revealed the presence of a de novo R1066H mutation on the affected chromosome of paternal origin. Three additional rare mutations (R1066C, R1066S and R1066L), occurring at the CpG dinucleotide at position 3328-3329 of the cystic fibrosis transmembrane conductance regulator gene, have so far been reported. The identification of a R1066H de novo mutation further suggests that this dinucleotide may constitute a mutational hotspot.
