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 made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.73).
BP6
Variant 6-156778607-C-T is Benign according to our data. Variant chr6-156778607-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 434368.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=-0.258 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00017 (25/147454) while in subpopulation NFE AF= 0.000316 (21/66436). AF 95% confidence interval is 0.000211. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High AC in GnomAd4 at 25 AD gene.
