Genes affected
KCTD13 (HGNC:22234): (potassium channel tetramerization domain containing 13) Enables identical protein binding activity and small GTPase binding activity. Contributes to ubiquitin-protein transferase activity. Involved in several processes, including cellular protein metabolic process; negative regulation of Rho protein signal transduction; and stress fiber assembly. Located in nuclear body. Part of Cul3-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.386T>G (p.L129R) alteration is located in exon 2 (coding exon 2) of the KCTD13 gene. This alteration results from a T to G substitution at nucleotide position 386, causing the leucine (L) at amino acid position 129 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
