Other Details
|
The mutation was deteceted by direct DNA sequencing and is a single bas (guanine) insertion after the stretch of four adenines in codons 335 & 336. The 1138insG mutation was seen on a chromosome with the 'C haplotype; i.e. XV2c type 2 and KM19 type 1. The mutation was seen in a boy from the North-West of England who was born with meconium ileus.
Although we have only seen this mutation once so far, its presence has been confirmed by sequencing from both the 5' and 3' ends of the exon and we believe that the disruption of the reading frame is suggestive of a CF mutation.
