Description

This variant has been observed in individual(s) with CANDLE syndrome (PMID: 21953331). ClinVar contains an entry for this variant (Variation ID: 29862). For these reasons, this variant has been classified as Pathogenic. Studies have shown that this variant alters PSMB8 gene expression (PMID: 26524591). This variant is present in population databases (rs146254972, ExAC 0.007%). This sequence change creates a premature translational stop signal (p.Cys135*) in the PSMB8 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PSMB8 are known to be pathogenic (PMID: 26524591).
