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

Apr 13, 2022

The c.242G>A (p.R81H) alteration is located in exon 2 (coding exon 2) of the KCTD14 gene. This alteration results from a G to A substitution at nucleotide position 242, causing the arginine (R) at amino acid position 81 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
