Genes affected

KLHDC2 (HGNC:20231): (kelch domain containing 2) Enables ubiquitin ligase-substrate adaptor activity. Involved in ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Located in nuclear body and nuclear membrane. Is active in Cul2-RING ubiquitin ligase complex and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

KLHDC2 links:

NEMF (HGNC:10663): (nuclear export mediator factor) This gene encodes a component of the ribosome quality control complex. The encoded protein facilitates the recognition and ubiquitination of stalled 60S subunits by the ubiquitin ligase listerin. A similar protein in fly functions as a tumor suppressor.

The c.982G>A (p.D328N) alteration is located in exon 11 (coding exon 11) of the KLHDC2 gene. This alteration results from a G to A substitution at nucleotide position 982, causing the aspartic acid (D) at amino acid position 328 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
