Genes affected
ADAMTSL2 (HGNC:14631): (ADAMTS like 2) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) and ADAMTS-like 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 protein encoded by this gene lacks the protease domain, and is therefore of a member of the the ADAMTS-like protein subfamily. It is a secreted glycoprotein that binds the cell surface and extracellular matrix; it also interacts with latent transforming growth factor beta binding protein 1. Mutations in this gene have been associated with geleophysic dysplasia. [provided by RefSeq, Feb 2009]

Variant summary: ADAMTSL2 c.340G>A (p.Glu114Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 6.4e-06 in 155966 control chromosomes. c.340G>A has been reported in the literature in multiple individuals affected with Geleophysic Dysplasia as a homozygous, compound heterozygous, or unspecified genotype (e.g. Allali_2011, LeGoff_2008, Li_2017, Marzin_2021), including a de novo occurrence in a compound heterozygous individual (Li_2017). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 21415077, 18677313, 28917829, 33082559). ClinVar contains an entry for this variant (Variation ID: 695). Based on the evidence outlined above, the variant was classified as pathogenic. -
