Phenotypes
Cataract, recessive, CPAMD8-related — Morgagnian cataract
Hollmann et al. (2017): "Whole genome re-sequencing of one case and four relatives showed a nonsense mutation (g.5995966C>T) in the PZP-like, alpha-2-macroglobulin domain containing 8 (CPAMD8) gene leading to a premature stop codon (CPAMD8 p.Gln74*)".
Factor XIII deficiency, F13A1-related
Shibutani et al. (2023) list a causal variant for F13 deficiency in Japanese Black cattle in the F13A1 gene as BTA23:g.48649432T>C, c.248T>C; p.F83S based on the publication by Ogawa and Iga (1996). Matsumoto et al. (2023) detected this variant in the Kumamoto sub-breed of Japanese Brown cattle.
Haplotype with homozygous deficiency HH1, APAF1-related — Haplotype HH1
Adams et al. (2012) revealed the causal mutation of HH1 as "a nonsense mutation in APAF1 . . . , which is predicted to truncate approximately one-third of the encoded APAF1 protein". Because functional APAF1 peptide is required for embryo development, homozygosity for this allele results in natural spontaneous abortion, and, consequently, perceived reduced fertility in carrier bulls that happen to be mated to carrier cows. Adams et al. (2016) ...
Haplotype with homozygous deficiency HH3, SMC2-related — Haplotype HH3
Using inferred haplotypes from the 1000-bull-genomes project, Hayes et al. (2013) announced the discovery of the likely HH3 causal mutation. Using exome capture and next-gen sequencing, McClure et al. (2014) confirmed and validated Hayes et al. (2013)'s causal mutation mutation as "a non-synonymous SNP (T/C) within exon 24 of the Structural Maintenance of Chromosomes 2 (SMC2) on Chromosome 8 at position 95,410,507 (UMD3.1). This polymorphism ...
