OMIA 001400-9940 : Chondrodysplasia, Texel in Ovis aries

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2012

Mapping: Using the ovine SNP50 BeadChip, Zhao et al. (2012) mapped this disorder to a 1Mb region on chromosome OAR4.

Molecular basis: Zhao et al. (2012) reported the causal mutation as being "a one base pair deletion, T (JN108880:g.25513delT) at the 107 bp position of exon 3" of the SLC13A1 gene.

Clinical features: "Disproportionate dwarfism, a stocky appearance with shortened neck and limbs, bilateral varus deformities of the forelimbs, flexion of the carpal joints, a barrel-shaped chest and wide-based stance" (Zhao et al., 2012)

Breed: Texel.

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.
