Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_014614.3(PSME4):​c.5473A>G​(p.Thr1825Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

• Frequency: Genomes: not found (cov: 32)
• Consequence: PSME4 NM_014614.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.95

Genes affected

PSME4 (HGNC:20635): (proteasome activator subunit 4) Predicted to enable lysine-acetylated histone binding activity; peptidase activator activity; and proteasome binding activity. Predicted to be involved in DNA repair; proteasomal ubiquitin-independent protein catabolic process; and spermatogenesis, exchange of chromosomal proteins. Located in nucleoplasm.
