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]

The p.A8P variant (also known as c.22G>C), located in coding exon 1 of the ARID1B gene, results from a G to C substitution at nucleotide position 22. The alanine at codon 8 is replaced by proline, an amino acid with highly similar properties. This amino acid position is conserved on limited sequence alignment. In addition, this alteration is predicted to be tolerated by SIFT in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
