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]

For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Experimental studies have shown that this missense change affects ZMPSTE24 function (PMID: 17152860, 22718200). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). ClinVar contains an entry for this variant (Variation ID: 140540). This missense change has been observed in individual(s) with mandibuloacral dysplasia with lipodystrophy (PMID: 15937076, 17152860, 25629449, 30919593). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs281875371, gnomAD 0.003%). This sequence change replaces asparagine with serine at codon 265 of the ZMPSTE24 protein (p.Asn265Ser). There is a small physicochemical difference between asparagine and serine.
