602421.0006; CYSTIC FIBROSIS |
| Identified Mutation |
ARG347PRO; In a family identified as UT 1446, Dean et al. [Cell 61: 863-870 (1990)] found a C-to-G transversion at position 1172, resulting in substitution of proline for aspartic acid (R347P). The mutation destroyed an HhaI restriction site and created a NcoI site. |
