The percentage of mutations found at each mutation hotspot shown for the labs in Leeds and Cardiff
| Assay | Leeds (% mutations) | Cardiff (% mutations) |
|---|---|---|
| KRAS codons 12/13 | 32/97 (33) | 31*/94 (33) |
| KRAS codon 61 | 3/96 (3.1) | 3/95 (3.2) |
| KRAS codon 146 | 1/95 (1.1) | 1/92 (1.1) |
| BRAF codon 600 | 12/96 (12.5) | 12/94 (12.8) |
| NRAS codons 12/13 | 2/95 (2.1) | 2/93 (2.1) |
| NRAS codon 61 | 2/95 (2.1) | 2/95 (2.1) |
| PIK3CA codons 542–546 | 10/95 (10.5) | 9/94 (9.6) |
| PIK3CA codon 1047 | 1/96 (1.0) | 2/93 (2.1) |
The percentages reflect the number of samples which yielded a result.
*The discrepancy in mutation detection at KRAS codons 12/13 is due to the fact that one of the samples which failed testing in Cardiff was found to have a mutation when tested successfully in Leeds.
