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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 30584). This premature translational stop signal has been observed in individual(s) with restrictive dermopathy (PMID: 16297189, 24169522). This variant is present in population databases (rs762551336, gnomAD 0.05%). This sequence change creates a premature translational stop signal (p.Ile19Tyrfs*28) 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). -
