Cross-species summary: Renamed, previously listed as 'Abortion (embryonic lethality), BTBD17-related' [12/06/2023]

Species-specific description: See also 'OMIA:000901-9615 : XX difference of sexual development, generic in Canis lupus familiaris' for the association of the BTBD17 variant with differences in sexual development.

Inheritance: Meyers-Wallen et al. (2017): "Because genotyping results at the 6048201 locus indicated that the G+G+ [homozygous for the G insertion] genotype was uncommon in XX DSD purebred pet dogs (3% G+G+, . . . ), but common in mixed breed XX DSD in the model pedigree (83% G+G+, . . . ), we hypothesized this genotype was deleterious in purebred dogs. Therefore, we genotyped pedigrees from purebred and crossbred breeding experiments in which the probability of G+G+ offspring varied from 0.25–0.5 . . . . All offspring were born alive and birth weights within the same litter were similar. None of the offspring were G+G+ genotype, including crossbred offspring sired by males from the model pedigree that had previously produced G+G+ and G+/- XX DSD offspring (sires C734 and C752, . . . ). These results indicated that embryonic lethality was associated with the G+G+ genotype in the GSHP genetic background."

Molecular basis: Meyers-Wallen et al. (2017) reported that the homozygous genotype for a variant in intron 1 of the BTBD17 gene ("a guanine insertion (G+) at CFA9: 6048201–6048202 . . . , rs852549625)") is associated with embryonic lethality in dogs with German shorthair pointer background. Meadows et al. (2023) investigated the presence of 463 likely causal variants in whole genome sequencing data of dogs in the Dog10K collection and identified that the BTBD17 variant reported by Meyers-Wallen et al. (2017) was homozygous in 179 dogs and heterozygous in 407 dogs from various breeds, while 1172 dogs were homozygous for the wildtype allele. The variant is therefore unlikely to be causal, and the association with homozygous lethality may be specific to German Shorthaired Pointers.

Breed: German Shorthaired Pointer (Dog) (VBO_0200583).

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.
