Genetic Variant ARID1B:p.Gln204_Gln205insGlnGlnGlnGlnGlnGlnGlnGlnGlnGlnGln (chr6-156778268-C-CCAGCAGCAGCAGCAGCAGCAGCAGCAGCAACAG) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP3

The NM_001374828.1(ARID1B):c.611_612insGCAGCAACAGCAGCAGCAGCAGCAGCAGCAGCA(p.Gln204_Gln205insGlnGlnGlnGlnGlnGlnGlnGlnGlnGlnGln) variant causes a disruptive inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000132 in 151,256 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 INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. 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]
