Species-specific name: classical Ehlers-Danlos syndrome (cEDS), COL5A2-related; Ehlers-Danlos syndrome, classic type, 2
Species-specific symbol: cEDS, EDS
Species-specific description: This phene has been renamed from "Ehlers-Danlos syndrome, classic type, 2" to "classical Ehlers-Danlos syndrome (cEDS), COL5A2-related" in OMIA on the basis of the review on human Ehlers-Danlos syndromes by Malfait et al. (2020) [2/6/2022].
History: The likely causal variant reported by Jacinto et al. (2020) "represents the first report of a causal variant for cEDS [classical Ehlers-Danlos syndrome] in cattle and the first COL5A2‐related large animal model."
Molecular basis: Jacinto et al. (2020): "Whole‐genome sequencing (WGS) identified a most likely disease‐causing mutation in the COL5A2 gene. . . . Genetic analysis revealed a private heterozygous missense variant inCOL5A2 (c.2366G>T; p.Gly789Val) that was present only in the calf and dam."
Clinical features: Jacinto et al. (2020): "A 3‐day‐old female Holstein calf was referred because of easily induced skin detachment and hyperextensibility in the neck. A complete clinical investigation was performed in the calf, dam, and maternal‐grandmother. The calf and dam showed hyperextensibility of the neck skin and atrophic scarring; additionally, the calf presented skin fragility."
Pathology: Jacinto et al. (2020): "histopathology of biopsies from the calf and its dam showed that the collagen bundles in affected skin areas were wavy, short, thin, and surrounded by edema and moderate to severe acute hemorrhages."
Breed:
Holstein (black and white) (Cattle) (VBO_0000237).

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
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.
