Besides these mutations we have also identified several mutated cancer drug targets or genes that are associated with treatment outcome, including BRAF, KRAS, FGFR2 and MTOR, which might help to choose optimal drug combinations.
Second, comparative genomic evidence indicates that the synonymous mutations we have uncovered are the most common substitutions at those sites in closely related Pseudomonads (Fig. 6).
To perceive the KIT gene mutations, we have carried out PCR SSCP followed by direct DNA sequencing in 50 AML-M0 cases.
To provide further insight into the magnitude of the fitness effects associated with these mutations, we have examined the distribution of fitness effects fixed in other populations from the larger experiment20.
"What's hugely encouraging is that many of the key mutations we have identified are ones targeted by existing cancer drugs, meaning that we could be entering a new era of personalised cancer treatment," he said.
Among the new mutations, we have found a nonsense mutation in MTM1 (c.139C>T) on a severe case of a 2-year old boy affected by MTM, and a heterozygous mutation in DNM2 (c.1279T>G) on a sporadic childhood-onset 17-year old girl.
To explore the possible effects of missense mutations, we have mapped them onto the homology model of human ISPD derived from the structure of a related bacterial protein (CDP-ME synthase; 1VPA).
"Our results therefore suggest that the mitochondrial mutations we have uncovered will generally cause faster male ageing across the animal kingdom". They suggest this is because there is no evolutionary reason for the faults that affect males to be picked up - because mitochondria are passed down by females.
We'll talk about what we did over the weekend, and at times about weekend benders, but rarely discuss diseases, or mutations we have.
"Individually, the rare mutations we have found likely confer a high risk for the disease, and we think they will be important in the search to find new, more effective treatments," said Anne Bowcock, professor of genetics at the Washington University School of Medicine, who co-authored both papers.
In the following sections, we describe the conditional mutations we have characterized for each affected locus.
