Mutations in the BAF (SWI/SNF)-complex subunits (SMARCE1, SMARCB1, SMARCA4, SMARCA2, ARID1B, and ARID1A) have been shown to cause CSS. People diagnosed with BAF pathway related diseases are increasing, and ARID2 (NM_152641.4) is the least common of these genes. Mutations in the ARID2 gene is the cause for Coffin-Siris syndrome 6 (CSS6). By now only 16 individuals with CSS have been reported to have pathogenic variants in ARID2.
UNASSIGNED: In this article, we introduced two individuals with clinical features consistent with CSS6 (Coffin-Siris syndrome 6). This article increases the number of reported cases, provides better phenotypic information for this rare syndrome, and allows everyone to better understand the disease.
UNASSIGNED: Our observations indicate that ARID2 mutations could have variable phenotypes, even in patients from the same family.
