History: This form of proportionate dwarfism in Fleckvieh cattle was first reported by Gottwald (1967).

Mapping: In a preprint posted on the Cold Spring Harbor bioRxiv preprint server on 15th January 2016, Schwarzenbacher et al. (2016) reported mapping this autosomal recessive disorder to a "1.85 Mb segment (14.88 Mb – 16.73 Mb)" segment of chromosome BTA3. A peer-reviewed version of this paper (by the same authors; see list below) was published on 31 March.

Molecular basis: In a preprint posted on the Cold Spring Harbor bioRxiv preprint server on 15th January 2016, Schwarzenbacher et al. (2016) documented the likely causal mutation as a 1bp frameshift deletion on chromosome BTA3: rs723240647, g.15079217delC, ENSBTAT00000027126:c.4285_4287delCCCinsCC, p.Glu1430LysfsX66 in exon 20 of the GON4L gene. A peer-reviewed version of this paper (by the same authors; see list below) was published on 31 March.

Clinical features: As reported by Schwarzenbacher et al. (2016): "Twenty-seven calves (16 males and 11 females) with strikingly low birth weight (~15kg) and size despite normal gestation length were noticed among the descendants of an artificial insemination bull. Four affected calves were clinically and pathologically examined. At age 61, 97, 101 and 143 days, they were underweight at 42, 79, 53 and 51 kg, respectively. The calves had multiple craniofacial aberrations (i.e., brachygnatia inferior, elongated narrow heads, structural deformities of the muzzle) and spinal distortions. Wrinkled skin, areas with excessive skin and a disproportionately large head became evident during rearing . . . . Although the general condition, feed intake and locomotion of the animals were normal, their growth remained restricted. The average weight gain of an affected animal during a hospitalisation period of 400 days was only 450 g per day, i.e. less than half the weight gain of healthy Fleckvieh bulls."

Breed: Fleckvieh.

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.
