Exome sequencing identified a novel HIST1H1E heterozygous protein-truncating variant in a 6-month-old male patient with Rahman syndrome: A case report.

Rahman syndrome is a rare congenital anomaly syndrome recently described, which results from pathogenic variants in the HIST1H1E gene. The condition is characterized by variable somatic overgrowth, macrocephaly, distinctive facial features, intellectual disability, and behavioral problems.
