Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP3BP6_Very_StrongBS2

The NM_001374828.1(ARID1B):​c.612_626delACAGCAGCAGCAGCA​(p.Gln205_Gln209del) variant causes a disruptive inframe deletion change. The variant allele was found at a frequency of 0.000103 in 1,540,474 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. Q204dup) has been classified as Uncertain significance.

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]
