Genes affected
ARID1B (HGNC:18040): (AT-rich interaction domain 1B) This locus encodes an AT-rich DNA interacting domain-containing protein. The encoded protein is a component of the SWI/SNF chromatin remodeling complex and may play a role in cell-cycle activation. The protein encoded by this locus is similar to AT-rich interactive domain-containing protein 1A. These two proteins function as alternative, mutually exclusive ARID-subunits of the SWI/SNF complex. The associated complexes play opposing roles. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]

Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Nov 02, 2017 | The c.1392_1402dup11 pathogenic variant in the ARID1B gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The c.1392_1402dup11 variant causes a frameshift starting with codon Glutamine 468, changes this amino acid to a Arginine residue, and creates a premature Stop codon at position 38 of the new reading frame, denoted p.Gln468ArgfsX38. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.1392_1402dup11 variant is not observed in large population cohorts (Lek et al., 2016). We interpret c.1392_1402dup11 as a pathogenic variant. - |
