Categories: Mortality / aging (incl. embryonic lethal)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive lethal

Disease-related: yes

Key variant known: no

Mapping: By genotyping each of 7,937 Nordic Holstein bulls with the BovineSNP50 BeadChip, yielding 36,387 informative autosomal SNPs, and then searching for 25-marker haplotypes that never occur as a homozygote where the minimum expectation is 6 occurrences, Sahana et al. (2013) "identified 17 homozygote deficient haplotypes which could be loosely clustered into eight genomic regions harboring possible recessive lethal alleles". One of these eight regions is haplotype 19-151 located between 13.2 and 14.5 Mb on chromosome BTA19.

Breed: Holstein (black and white) (Cattle) (VBO_0000237).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).
