Genes affected
ADAMTS17 (HGNC:17109): (ADAM metallopeptidase with thrombospondin type 1 motif 17) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) protein family. ADAMTS family members 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 protein, which may promote breast cancer cell growth and survival. Mutations in this gene are associated with a Weill-Marchesani-like syndrome, which is characterized by lenticular myopia, ectopia lentis, glaucoma, spherophakia, and short stature.

Likely pathogenic, criteria provided, single submitterclinical testingInvitaeNov 16, 2023This sequence change affects a donor splice site in intron 12 of the ADAMTS17 gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or disrupted protein product. This variant is present in population databases (rs749116256, gnomAD 0.006%). Disruption of this splice site has been observed in individual(s) with clinical features consistent with Weill-Marchesani-like syndrome (PMID: 19836009). ClinVar contains an entry for this variant (Variation ID: 3155). Studies have shown that disruption of this splice site results in skipping of exon 12 and introduces a premature termination codon (PMID: 19836009). The resulting mRNA is expected to undergo nonsense-mediated decay. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
