Genes affected

PSMA4 (HGNC:9533): (proteasome 20S subunit alpha 4) This gene encodes a core alpha subunit of the 20S proteosome, which is a highly ordered ring-shaped structure composed of four rings of 28 non-identical subunits. Proteasomes cleave peptides in an ATP- and ubiquitin-dependent manner. [provided by RefSeq, Aug 2016]

The c.698T>C (p.V233A) alteration is located in exon 9 (coding exon 8) of the PSMA4 gene. This alteration results from a T to C substitution at nucleotide position 698, causing the valine (V) at amino acid position 233 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
