Two years after identifying the V617F mutation, the first specific JAK2 inhibitors were designed.
Researchers were rather on a quest for the opposite situation, where one crippling mutation is rescued by a second, intragenic, suppressor mutation, the second restoring the function lost due to the first mutation [ 19, 20].
Progression to frank and active disease would require a second somatic mutation (the second "hit") in the remaining allele in the affected tissue type.
Plasmid M1 has a single point mutation; the second 'T' in the HMG domain-binding region was substituted with an 'A'.
The T294M mutation is the first mutation to be shown to selectively abolish the ability of MgADP to stimulate channel activity in the presence of MgATP.
The c.700C>T, p.Arg234Cys mutation is the first mutation in which arginine is replaced by cysteine in the triple helical domain of proα2(I).
The mutation in the third PDZ domain of whirlin in humans causes the sensorineural deafness disorder (DFNB31).

The presence of a JAK2 mutation remains the third major diagnostic criterion in PV.
In particular, we examine the waiting time for a pair of mutations, the first of which inactivates an existing transcription factor binding site and the second of which creates a new one.
