11ET patients, 16 PMF patients, and 20PV patients”,

It should read:

“12 ET patients, 17 PMF patients, and 23PV patients”

In Table 1, ET column, where it reads:

5, it should read 6 (Male line) and where it reads 4, it should read 6 (Female line).

In Figure 1 legend, where it reads:

“essential thrombocythemia (ET; n=11), primary myelofibrosis (PMF; n=16), and polycythemia vera (PV; n=20).”,

It should read:

“essential thrombocythemia (ET; n=12), primary myelofibrosis (PMF; n=17), and polycythemia vera (PV; n=23).”

In Figure 2 legend, where it reads:

“MF patients (n=11)”,

It should read:

“MF patients (n=12)”

In Figure 5 legend, where it reads:

“myelofibrosis patients (n=16)”,

It should read:

“myelofibrosis patients (n=15)”
