KCTD14 (HGNC:23295): (potassium channel tetramerization domain containing 14) Predicted to be involved in protein homooligomerization. [provided by Alliance of Genome Resources, Apr 2022]

KCTD14 links:

NDUFC2-KCTD14 (HGNC:42956): (NDUFC2-KCTD14 readthrough) This locus represents naturally occurring read-through transcription between the neighboring NDUFC2 (NADH dehydrogenase (ubiquinone) 1, subcomplex unknown, 2, 14.5kDa) and KCTD14 (potassium channel tetramerisation domain containing 14) genes on chromosome 11. The read-through transcripts share sequence identity with the upstream gene product and one variant has a frameshifted C-terminal region derived from the downstream gene exons.

Ambry Genetics

Jun 16, 2024

The c.327G>T (p.E109D) alteration is located in exon 2 (coding exon 2) of the KCTD14 gene. This alteration results from a G to T substitution at nucleotide position 327, causing the glutamic acid (E) at amino acid position 109 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
