It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NDUFAF5 are known to be pathogenic (PMID: 26275793, 30473481, 32918965). This variant is present in population databases (rs148305100, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with NDUFAF5-related conditions. ClinVar contains an entry for this variant (Variation ID: 2141503). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. (less)

Comment:

This sequence change creates a premature translational stop signal (p.Arg276*) in the NDUFAF5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NDUFAF5 are known to be pathogenic (PMID: 26275793, 30473481, 32918965). This variant is present in population databases (rs148305100, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with NDUFAF5-related conditions. ClinVar contains an entry for this variant (Variation ID: 2141503). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
