| CYSTIC FIBROSIS GENE: RFLP HAPLOTYPES & MUTATION STUDIES |
Cystic fibrosis gene alleles are 621+1 G>T & 711+1 G>T: splice mutation G>T at nucleotide 621+1 in intron 4 & splice mutation G>T at nucleotide 711+1 in intron 5. |

| CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR |
The CFTR gene mutation data for this repository number was verified by sequencing. |
| |
| GENE MAPPING & DOSAGE STUDIES - Y CHROMOSOME |
PCR analysis of DNA from this cell culture gave a negative result with a primer for Yq11, DYS227. |

| Identified Mutation |
621+1G>T |
| Remarks |
Donor subject is a compound heterozygote: one allele of the CFTR gene carries a G-to-T substitution at 711+1 in intron 5 (711+1 G>T); a second allele of the CFTR gene carries a G-to-T substitution at 621+1 in intron 4 (621+1G>T); both mutations result in mRNA splicing defects; analysis of a DNA variant in a noncoding region of the CFTR gene (polypyrimidine tract in intron 8) showed this donor has alleles 7T/9T |
