This sequence change creates a premature translational stop signal (p.Pro16Serfs*45) in the PSMB4 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in PSMB4 cause disease. This variant is present in population databases (no rsID available, gnomAD 0.006%). 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. ClinVar contains an entry for this variant (Variation ID: 548957). This premature translational stop signal has been observed in individual(s) with clinical features of chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome (PMID: 26524591). -
