Genes affected

PSMD10 (HGNC:9555): (proteasome 26S subunit, non-ATPase 10) This gene encodes a subunit of the PA700/19S complex, which is the regulatory component of the 26S proteasome. The 26S proteosome complex is required for ubiquitin-dependent protein degradation. This protein is a non-ATPase subunit that may be involved in protein-protein interactions. Aberrant expression of this gene may paly a role in tumorigenesis. Two transcripts encoding different isoforms have been described. Pseudogenes have been identified on chromosomes 3 and 20.[provided by RefSeq, Mar 2011]

Mar 21, 2023

The c.547G>A (p.E183K) alteration is located in exon 5 (coding exon 5) of the PSMD10 gene. This alteration results from a G to A substitution at nucleotide position 547, causing the glutamic acid (E) at amino acid position 183 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
