Happy Monday-
I have a newborn patient with bowel obstruction and elevated IRT whose DNA studies show she is compound heterozygous for deltaF508/L1254X.  Parents of course wanting clinical correlation.  As far as I can find, the L1254X mutation has only been reported in one English patient, in a personal communication between Wallace and Tassabehji in 1993.  If anyone else has seen this mutation and can give any type of clinical correlation I would welcome it.

Thanks,
Robin
