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]

Pathogenic, criteria provided, single submitterclinical testingGeneDxMay 05, 2017The c.50delA variant in the ZMPSTE24 gene has been reported previously in association with restrictive dermopathy when present in the homozygous state or when in trans with another loss-of-function variant (Smigiel et al., 2010; Navarro et al., 2014; Matuleviciene et al., 2016). The c.50delA variant causes a frameshift starting with codon Lysine 17, changes this amino acid to a Serine residue, and creates a premature Stop codon at position 21 of the new reading frame, denoted p.Lys17SerfsX21. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.50delA variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Therefore, we interpret c.50delA as a pathogenic variant. -
Pathogenic, criteria provided, single submitterclinical testingInvitaeSep 01, 2021This sequence change creates a premature translational stop signal (p.Lys17Serfs*21) 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 not present in population databases (ExAC no frequency). This premature translational stop signal has been observed in individual(s) with restrictive dermopathy (PMID: 20101687, 26379196). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 41411). For these reasons, this variant has been classified as Pathogenic. -
