Furthermore, only the two previously reported missense changes (Ser217Leu and Ala541Thr) were identified by mutational analysis of all HPC2/ELAC exons in 93 probands with HPC.
We conclude that ELAC2/HPC2 truncating mutations are rare in HPC, but that rare variants of the ELAC2/HPC2 require additional study as risk factors for PRCA in the general population.
