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.130A>T (p.T44S) alteration is located in exon 1 (coding exon 1) of the KCTD17 gene. This alteration results from a A to T substitution at nucleotide position 130, causing the threonine (T) at amino acid position 44 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
