RYR1 and transient myeloproliferative syndrome: An additional intriguing aspect emerging from the data we are reporting is that the allele frequency in the general population of the two causative RYR1 mutations (1:47,102 and 1:25,696 for p.Thr2206Met and p.Gly2434Arg, respectively) is much higher than the frequency of a very rare disease such as TAM (Conte et al., 2021; Silva‐Rojas et al., 2020).
