ABSTRACT
OBJECTIVE@#To explore the genetic basis for two Chinese pedigrees affected with Coffin-Siris syndrome (CSS).@*METHODS@#Whole exome sequencing (WES) was carried out for the probands. Candidate variants were verified by Sanger sequencing of the probands and their family members.@*RESULTS@#The two probands were respectively found to harbor a heterozygous c.5467delG (p.Gly1823fs) variant and a heterozygous c.5584delA (p.Lys1862fs) variant of the ARID1B gene, which were both of de novo in origin and unreported previously. Based on the guidelines of American College of Medical Genetics and Genomics, both variants were predicted to be pathogenic (PVS1+PS2+PM2).@*CONCLUSION@#The c.5467delG (p.Gly1823fs) and c.5545delA (p.Lys1849fs) variants of the ARID1B genes probably underlay the CSS in the two probands. Above results have enabled genetic counselling and prenatal diagnosis for the pedigrees.
