Genes affected

BTBD16 (HGNC:26340): (BTB domain containing 16) This gene encodes a protein that contains a BTB/POZ domain. This domain mediates protein-protein interactions. A mutation in this gene may be associated with bipolar disorder. [provided by RefSeq, Sep 2016]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.04829535).
