CF databases: c.1705T>G , p.Tyr569Asp D , CF-causing ; CFTR1: Y569D was identified by direct DNA sequencing. The mutation was found in three Pakistani patients, presumed to be unrelated; all were from consanguineous partnerships and all homozygous for the mutation. 60 non-[delta]F508 chromosomes, of which 12 were Pakistani in origin, were negative for Y569D
c.1705T>C , p.Tyr569His (CFTR1) D , This missense mutation was detected by DGGE and identified by sequence analysis. This substitution would result in a histidine at position 569. The mutation was found on a haplotype A in a young [delta}F508 heterozygous French patient.
c.1706A>G , p.Tyr569Cys (CFTR1) ? , The mutation was detected by SSCP analysis, followed by direct sequencing of amplified DNA using the primers 5'-GTGAATCGATGTGGTGACCA-3' and 5'-CTATGATGGGACAGTCTG-3'. It can not be detected by restriction enzyme analysis. The mutation was seen in a girl from the Republic of Croatia, whose other CF chromosome carries the [delta]F508 mutation. The Y569C mutation was not found among 84 CF (17[delta]F508) and among 12 normal chromosomes.
