Genes affected
KCTD3 (HGNC:21305): (potassium channel tetramerization domain containing 3) This gene encodes a member of the potassium channel tetramerization-domain containing (KCTD) protein family. Members of this protein family regulate the biophysical characteristics of ion channels. In mouse, this protein interacts with hyperpolarization-activated cyclic nucleotide-gated channel complex 3 and enhances its cell surface expression and current density. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.97A>G (p.R33G) alteration is located in exon 2 (coding exon 2) of the KCTD3 gene. This alteration results from a A to G substitution at nucleotide position 97, causing the arginine (R) at amino acid position 33 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
