	        | cDNA Name | c.2988+1G>A |  
	        | Exon or Intron | intron 18 |

	        |  | 3120+1G->A |  
	        | Other Details | The mutation, 3120+1G->A was not seen in 188 normal African-American and 13 non-CF African-American chromosomes.  This mutation was not seen in 160 Caucasian CF chromosomes screened by DGGE (NL#56).
This mutation accounts for 12.7% of African-American CF alleles and is the most common after [delta]F508.  Its presence on a native African CF chromosome and absence on Caucasian CF chromosomes suggests that this is of African origin (Ref: Macek et al., AJHG 60: 112-1127, 1997)
This mutation has also been found in South African, Saudi Arab and Greek patients.  Please see Dork et al. AJHG 63: 656-662. 1998. |
