Genes affected

KCTD17 (HGNC:25705): (potassium channel tetramerization domain containing 17) This gene encodes a protein that belongs to a conserved family of potassium channel tetramerization domain (KCTD)-containing proteins. The encoded protein functions in ciliogenesis by acting as a substrate adaptor for the cullin3-based ubiquitin-conjugating enzyme E3 ligase, and targets trichoplein, a keratin-binding protein, for degradation via polyubiquitinylation. A mutation in this gene is associated with autosomal dominant myoclonic dystonia 26. [provided by RefSeq, Nov 2016]

The c.53C>T (p.P18L) alteration is located in exon 1 (coding exon 1) of the KCTD17 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the proline (P) at amino acid position 18 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
