KCTD16

protein-coding

potassium channel tetramerization domain containing 16, the group of KCTD family

Gene summary

Predicted to enable obsolete G protein-coupled neurotransmitter receptor activity involved in regulation of postsynaptic membrane potential and obsolete G protein-coupled neurotransmitter receptor activity involved in regulation of presynaptic membrane potential. Predicted to be involved in regulation of G protein-coupled receptor signaling pathway. Predicted to act upstream of or within behavioral fear response and memory. Predicted to be part of signaling receptor complex. Predicted to be active in postsynaptic membrane and presynaptic membrane. [provided by Alliance of Genome Resources, Jun 2026]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_020768.4. 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 subunit of GABA-B receptors that determine the pharmacology and kinetics of the receptor response. Increases agonist potency and markedly alter the G-protein signaling of the receptors by accelerating onset and promoting desensitization (By similarity). {ECO:0000250|UniProtKB:Q5DTY9}.;
