ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_001013653.3. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

- Function
- FUNCTION: Auxiliary protein of the large-conductance, voltage and calcium-activated potassium channel (BK alpha). Required for the conversion of BK alpha channels from a high-voltage to a low- voltage activated channel type in non-excitable cells. These are characterized by negative membrane voltages and constant low levels of calcium. {ECO:0000269|PubMed:20613726, ECO:0000269|PubMed:22547800}.;
