Table 1 Frequency of the RP1 frameshift allele among breeds represented in run4 of the 1000 bull genomes project

From: A reverse genetic approach identifies an ancestral frameshift mutation in RP1 causing recessive progressive retinal degeneration in European cattle breeds

Breed Frequency of the RP1 frameshift allele in  % (number of genomes per breed with available genotype)
Aberdeen Angus 1.8 (140)
Beef Booster Composite 2.1 (2)
Belgian Blue 5.0 (10)
Charolais 3.8 (39)
Gelbvieh 1.4 (36)
Holstein 1.8 (312)
Maine-Anjou 14.3 (7)
Normande 28.3 (23)
Red Angus 7.0 (28)
Run4 1.8 (1137)
  1. The RP1 frameshift allele was absent from the Brown Swiss (n = 59), Finnish red (n = 25), Hereford (n = 34), Jersey (n = 60), Limousine (n = 33), Montbéliarde (n = 28), Simmental (n = 215) and Swedish Red (n = 31) breeds, which each totalized more than 20 animals in run4 of the 1000 bull genomes project and from 12 additional breeds, which each totalized less than 20 animals
