The importance of understanding HIST1H1E Syndrome is sharing our family's personal journey to find a diagnosis for our daughter, Bonnie Odgers. This syndrome has also been referred to as Rahman Syndrome and HIST1H1E Neurodevelopmental Syndrome depending upon the origin of research. Characteristics of HIST1H1E are curved fingers, full cheeks, high forehead, speech impairments and mild to severe intellectual disability. This article reveals the Odgers' family journey towards a diagnosis, the key physicians research through whole exome genetic testing and revealing characteristics of HIST1H1E.

A 2-year-old male patient with dysmorphic facial features and multiple congenital anomalies suggestive of a chromosome syndrome is presented. The facial features consisted of a large and high forehead, mild metopic ridging, a small triangular face, depressed nasal bridge, microphthalmia (right more than the left), protruding ears, and mildly prominent anteverted nose with long and smooth philtrum. Cytogenetic analysis showed 46,XY,del(20)(q11.2q12). Parental karyotypes were normal. Molecular characterization of del(20)(q11.2q12) by high-resolution microarray comparative genomic hybridization (arrayCGH) showed an approximately 6.8 Mb deletion. To our knowledge this is the first report of a de novo interstitial del(20)(q11.2q12) characterized by arrayCGH.
