OMIA 001716-9913 : Ehlers-Danlos syndrome, Holstein variant in Bos taurus

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 1999

Mapping: 5q21

Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on a related human disorder), Tajima et al., 1999 reported that this disorder in one affected Holstein calf is due to a missense mutation (G254A) in the gene for dermatan sulfate proteoglycan, resulting in a serine-to-asparagine substitution in the serine-glycine repeat portion of the peptide, which is the binding portion of the peptide. The peptide is now called epiphycan, and its gene is called EPYC. It turns out that the related human disorder (Ehlers-Danlos syndrome, progeroid form) is due to mutations in a different gene (B4GALT7).

Breed: Holstein.

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.
