				This mutation was seen in a 48 year-old male being investigated for infertility whose other CF mutation is [delta]F508. We have seen this mutation only once in over 200 CF chromosomes screened.(Original Note 27March2001)
Reported by Jennifer King (University of Iowa.  22/03/2002):
It was also found in a 12 year old male patient who was seen for genetic evaluation following discovery of CBAVD (during a hydrocele repair operation).  It turned out that he has a [delta]F508 mutation and a R170H mutation.  His sweat test was normal.

				2 patients, both with CBAVD, normal sweat chlorides, one of them born in 1950. Both have DelF508 on the other allele.
