Arachnomelia, SUOX-related
Having a good idea of the map location of the gene responsible for this disorder in Brown Swiss cattle, Drögemüller et al. (2010) used sequence capture followed by resequencing to identify a single base insertion in the gene for sulfite oxidase (SUOX) as being causative for this disorder in this breed. The synthesis of sulfite oxidase is dependent upon molybdenum cofactor (Moco), whose synthesis is dependent upon two peptides (MOCS1A and MOCS1...
Dwarfism, ACAN-related — Bulldog calf; chondrodysplasia
Information about ACAN related dwarfism in Bos indicus cattle was previously listed here and was moved to 'OMIA:001271-9915 : Dwarfism, ACAN-related in Bos indicus' [19/06/2023]
Haplotype with homozygous deficiency MH1
For eight of the nine haplotypes with a significant effect on calving rate (see Mapping section), Fritz et al. (2013) searched for causal mutations via whole-genome sequence data from 25 Holstein, 11 Montbéliarde and nine Normande bulls which had made major contributions to their breed. Specifically, they filtered "for mutations that were (a) located at+or –6 Mb from the detected haplotype (b) carried in the heterozygous state by the carrier b...

Ptosis, intellectual disability, retarded growth and mortality (PIRM) syndrome (Haplotype AH1) — Haplotype AH1
Comparison of sequence of the 713kb candidate region (mentioned in the mapping section above) in an obligate carrier, one of its offspring, 43 members of the Fleckvieh breed (in which the disorder has never been reported) and 191 non-Fleckviehs from the 1000-bulls project revealed 2 candidate causal SNVs: a coding variant and an intronic variant of the gene UBE3B, which encodes ubiquitin protein ligase E3B, and mutations in which cause a simil...
