Genes affected
ADAMTS2 (HGNC:218): (ADAM metallopeptidase with thrombospondin type 1 motif 2) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) protein family. Members of the family share several distinct protein modules, including a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. Individual members of this family differ in the number of C-terminal TS motifs, and some have unique C-terminal domains. The encoded preproprotein is proteolytically processed to generate the mature procollagen N-proteinase. This proteinase excises the N-propeptide of the fibrillar procollagens types I-III and type V. Mutations in this gene cause Ehlers-Danlos syndrome type VIIC, a recessively inherited connective-tissue disorder. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

This sequence change creates a premature translational stop signal (p.Gln225*) in the ADAMTS2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ADAMTS2 are known to be pathogenic (PMID: 10417273). This variant is present in population databases (rs137853146, gnomAD 0.3%). This premature translational stop signal has been observed in individuals with Ehlers-Danlos syndrome, type VIIC (PMID: 10417273, 18973246). ClinVar contains an entry for this variant (Variation ID: 5502). For these reasons, this variant has been classified as Pathogenic. -

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The ADAMTS2 c.673C>T (p.Gln225Ter) variant is a stop-gained variant that is predicted to result in a premature termination of the protein. The variant has been reported in a homozygous state in a total of six individuals with Ehlers-Danlos syndrome (Colige et al. 1999; Bar-Yosef et al. 2008). One of the newborn individuals exhibited multiple non-traumatic congenital skull fractures and multiple other defects related to a connective tissue abnormality (Bar-Yosef et al. 2008). Control data are unavailable for the p.Gln225Ter variant, which is reported at a frequency of 0.003053 in the Ashkenazi Jewish population of the Genome Aggregation Database. Due to the potential impact of stop-gained variants and the available evidence, the p.Gln225Ter variant is classified as pathogenic for Ehlers-Danlos syndrome, dermatosparaxis type. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
