Genes affected

ZMPSTE24 (HGNC:12877): (zinc metallopeptidase STE24) This gene encodes a member of the peptidase M48A family. The encoded protein is a zinc metalloproteinase involved in the two step post-translational proteolytic cleavage of carboxy terminal residues of farnesylated prelamin A to form mature lamin A. Mutations in this gene have been associated with mandibuloacral dysplasia and restrictive dermopathy. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Glu237*) in the ZMPSTE24 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ZMPSTE24 are known to be pathogenic (PMID: 22718200, 24169522). This variant is present in population databases (rs281875370, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ZMPSTE24-related conditions. ClinVar contains an entry for this variant (Variation ID: 140537). For these reasons, this variant has been classified as Pathogenic. -
