OMIA:000328-9940 : Dermatosparaxis Ehlers-Danlos syndrome (dEDS), ADAMTS2-related in Ovis aries
Categories: Integument (skin) phene
Links to MONDO diseases:
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2012
Species-specific name: Dermatosparaxis Ehlers-Danlos syndrome (dEDS), ADAMTS2-related; Ehlers-Danlos syndrome, type VII (Dermatosparaxis); dermatosparaxis
Species-specific symbol: dEDS; EDS
Species-specific description: Although evidence was incomplete, it appeared for many years that this disorder in sheep is due to a mutation in the gene for the enzyme procollagen I amino proteinase, this being the enzyme responsible for removing "surplus" amino acids from the N-terminal end of procollagen-I molecules.
This phene has been renamed from "Ehlers-Danlos syndrome, type VII (Dermatosparaxis)" to "Dermatosparaxis Ehlers-Danlos syndrome (dEDS), ADAMTS2-related" in OMIA on the basis of the review on human Ehlers-Danlos syndromes by Malfait et al. (2020) [2/6/2022].
Molecular basis: In 2012, Zhou et al. showed that the situation described in the Species-specific section above is, indeed, the case: the disorder in affected White Dorper sheep from New Zealand is due to a nonsense mutation (c.421G>T) in exon 2 of the gene encoding that procollagen proteinase. Unhelpfully, the gene is called ADAM metalloproteinase with thrombospondin type I motif, 2 (ADAMTS2).
Monteagudo et al. (2015) reported a second likely causal variant (c.805G>A; p.Val269Met) in the same gene, in an affected White Dorper from Spain.
Joller et al. (2017) reported an affected White Dorper in Switzerland with the same variant as reported in the New Zealand White Dorpers (now c.424G>T; p.Glu142*). This is consistent with the recent migration of White Dorpers from South Africa to many other countries.
Breed: Dorper (Sheep) (VBO_0001397).

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
