The authors only listed five of the genes which are known to cause Mendelian disorders that include a seizure phenotype – ASPM, CNTNAP2, GPR98, PCNT and POMGNT1. In our analysis using the 1000 Genomes Project participants as controls, enrichment for CH variants was not detected in any of these genes. The gene discussed is PCNT; the disease is cyclic hematopoiesis.
