case_images: The family pedigree of patient 1. The pedigree of the family with Coffin-Siris syndrome (CSS). (a) P1 ARID2 c.2610delT; (b) P1 father ARID2 gene c.2610T (wild type); (c) P1 mother ARID2 c.2610T (wild type). The mutation is de novo in the proband, whereas the parents are wild-type. The family pedigree of patient 2. The pedigree of the family with Coffin-Siris syndrome (CSS). (d) P2 father ARID2 c.674G (wild type); (e) P2 ARID2 c.674G > A; p. Trp225 *; (f) P2 mother ARID2 c.674G > A; p. Trp225 *.
