It is expected to result in an absent or disrupted protein product. Loss-of-function variants in XPA are known to be pathogenic (PMID: 27607234). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with XPA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1709507). For these reasons, this variant has been classified as Pathogenic. (less)

Comment:

This sequence change creates a premature translational stop signal (p.Gln174*) in the XPA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in XPA are known to be pathogenic (PMID: 27607234). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with XPA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1709507). For these reasons, this variant has been classified as Pathogenic.
