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]

Ambry Genetics

Jul 05, 2023

The c.19G>A (p.D7N) alteration is located in exon 1 (coding exon 1) of the KLHDC2 gene. This alteration results from a G to A substitution at nucleotide position 19, causing the aspartic acid (D) at amino acid position 7 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
