Genes affected

UBR7 (HGNC:20344): (ubiquitin protein ligase E3 component n-recognin 7) This gene encodes a UBR box-containing protein that belongs to the E3 ubiquitin ligase family. The protein also contains a plant homeodomain (PHD) in the C-terminus. In mammals, the encoded protein recognizes N-degrons, the destabilizing N-terminal residues of short-lived proteins, which results in ubiquitinylation, and proteolysis via the proteasome.

Aug 19, 2024

The c.22G>C (p.A8P) alteration is located in exon 1 (coding exon 1) of the UBR7 gene. This alteration results from a G to C substitution at nucleotide position 22, causing the alanine (A) at amino acid position 8 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
