Phenotypes

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...

By comparing whole-genome sequenced data (from 2 affecteds and one control) in the candidate region (see Mapping section), and filtering resultant candidate variants, Duchesne et al. (2018) narrowed the field down to "a single substitution in exon 5 of KIF1C (chr19:27041449 C/T). For easier comprehension and since KIF1C gene in cattle is on the reverse strand, the substitution will be referred as KIF1C G>A in order to match with the transcr...
