| CYSTIC FIBROSIS GENE: RFLP HAPLOTYPES & MUTATION STUDIES |
PROBE: metD metD metH metH XV-2c KM.19 pJ3.11 pJ3.11 JG ENZYME: BanI TaqI MspI TaqI TaqI PstI MspI TaqI PstI RESULTS: 2,2 1,1 3,3 2,2 1,2 2,2 1,2 1,1 1,2 F508 deletion mutation is one allele. Other allele is negative for F508, G551D, R553X, G542X, and N1303K mutations. The above results were kindly provided to the Repository by Dr. Arthur L. Beaudet, Baylor College of Medicine, Houston, TX. The F508 deletion result was confirmed by Dr. C. Goodpasture, VIVIGEN, Santa Fe, NM (personal communication). |

| Allelic Variant 1 |
602421.0001; CYSTIC FIBROSIS |

| Gene |
CFTR |
| Chromosomal Location |
7q31.2 |
| Allelic Variant 2 |
602421.0043; CYSTIC FIBROSIS |
| Identified Mutation |
1-BP DEL, 557T DEL, FS; In a patient with cystic fibrosis with relatively mild symptoms, Graham et al. (1992) identified deletion of a single nucleotide, a T, in the T tract from base 557 to 561 in exon 4 of the CFTR gene. Like the 556A deletion (602421.0042), the mutation created a new BglI site.

| Remarks |
Two sibs are also aff; diag at about age 6; moderate pulmonary & no gastrointestinal symp at the time of diag; no symps present at birth; on enzyme supplements; recombinant DNA haplotype between CF & MET; F508 deletion [PHE508DEL]/557delT mutations |
