Genes affected

PSMB6 (HGNC:9543): (proteasome 20S subunit beta 6) 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. The encoded protein is a member of the proteasome B-type family, also known as the T1B family, and is a 20S core beta subunit in the proteasome. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

Ambry Genetics

Jun 06, 2023

The c.130G>T (p.G44W) alteration is located in exon 2 (coding exon 2) of the PSMB6 gene. This alteration results from a G to T substitution at nucleotide position 130, causing the glycine (G) at amino acid position 44 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
