Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_144587.5(BTBD16):​c.20A>C​(p.His7Pro) variant causes a missense, splice region 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. 16/22 in silico tools predict a benign outcome for this variant. 2/2 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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 Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19905466).

The c.20A>C (p.H7P) alteration is located in exon 3 (coding exon 2) of the BTBD16 gene. This alteration results from a A to C substitution at nucleotide position 20, causing the histidine (H) at amino acid position 7 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
