Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001318189.3(BTBD16):​c.956G>T​(p.Arg319Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R319W) has been classified as Uncertain significance.

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

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09700671).
