ARID5B and Wolf-Hirschhorn syndrome: In addition, in individual 13, whose ARID5B candidate variant was found by GS, reverse phenotyping was not consistent with Wolf-Hirschhorn syndrome, and nor was a deletion in 4p16.3 found by array CGH and GS, suggesting that ARID5B mutation may share some molecular biomarkers in common with Wolf-Hirschhorn syndrome.
