Genes affected
PSMA3 (HGNC:9532): (proteasome 20S subunit alpha 3) The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a member of the peptidase T1A family, that is a 20S core alpha subunit. Two alternative transcripts encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
PSMA3-AS1 (HGNC:26445): (PSMA3 antisense RNA 1)
ARMH4 (HGNC:19846): (armadillo like helical domain containing 4) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 14, 2024This sequence change falls in intron 8 of the PSMA3 gene. It does not directly change the encoded amino acid sequence of the PSMA3 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs747982940, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with PSMA3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1382060). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
