Rahman syndrome (RMNS) is a recently described congenital anomaly syndrome characterized by variable somatic overgrowth, macrocephaly, distinctive facial features, intellectual disability, and behavioral problems. It has been reported that pathogenic variants in HIST1H1E (H1-4) cause this syndrome. HIST1H1E encodes the linker histone H1.4, a member of the H1 histone family, and functions as a structural component of chromatin to control DNA compaction, gene expression regulation, DNA replication, recombination, and repair.
