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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.6).
BP6
Variant 6-157207735-G-A is Benign according to our data. Variant chr6-157207735-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 210308.
BP7
Synonymous conserved (PhyloP=-0.717 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000899 (129/1435462) while in subpopulation AMR AF = 0.00127 (55/43274). AF 95% confidence interval is 0.001. There are 1 homozygotes in GnomAdExome4. There are 52 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
