double-muscled Gelbvieh cattle. In silico analysis of this mutation using POLYPHEN (http://genetics.bwh.harvard.edu/ pph2/) and SIFT (http://siftdna.org/www/Extended_SIFT_ chr_coords_submit.html) predicted a probably damaging effect on the protein. The amino acid leucin at position 64 of the MSTN protein is highly conserved among mammals (Fig. S1). The two double-muscled Gelbvieh cattle had one copy of the c.191T>C mutation and one copy of the 11-bp deletion. Genotyping of their parents confirmed compound heterozygosity of the c.191T>C and the 11-bp deletion mutation in these two animals (Fig. 1). All four parents were heterozygous for each one of the two mutations. In one case, the novel exon 1 mutation was transmitted by the sire and in the second case by the dam. The other two double-muscled Gelbvieh cattle were homozygous for the 11-bp deletion. Validation of the c.191T>C and c.821del11 mutations in 451 individuals revealed 19 Glanrind, seven German Gelbvieh and five Limpurger cattle as heterozygous for the c.191T>C mutation (Table S3). Of 29 double-muscled animals, 27 were homozygous for the 11-bp deletion and two for the mutation resulting in p.Cys313Tyr. Allele frequencies for c.191T>C were at 0.03 in German Gelbvieh and Limpurger, but at 0.10 in Glanrind (Table 1). Allele frequencies for the 11-bp deletion were 0.94 in Belgian Blue, 0.16 in German Angus, 0.07 in German Gelbvieh and 0.01 in Limpurger. The previously reported p.Phe94Leu variant from exon 1 of MSTN was associated with increased muscle mass in Limousin.6 In contrast to the novel detected mutation, the mutation resulting in the p.Phe94Leu substitution is located in a less conserved region (Fig. S1). The high frequency of 0.10 in Glanrind might be indicative of an origin of this mutation in the Glanrind and spreading through Glanrind sires into other breeds such as Gelbvieh and Limpurger. Our study showed a novel mutation with a probably damaging effect on the protein function of MSTN. We could validate this mutation in German Gelbvieh, Glanrind and Limpurger. Testing these breeds for the novel c.191T>C and 11-bp deletion mutations should be effective in preventing double-muscled animals.

Brief Notes breeds that are part of the Podolian and Brachicerous (Busha) cattle groups respectively. Concerning the mtDNA diversity of Balkan cattle breeds, previous studies focused on Busha cattle and Grey cattle populations.1 These investigations referred to the origin and worldwide migration of taurine breeds, and the Balkans were pointed out as an important route for European cattle dissemination. The aim of this study was to establish the mitochondrial D-loop genetic diversity of BGC and SRC and to reveal their state among other European Podolian and Brachicerous cattle breeds. Genotyping and sequence analysis: Two sets of 20 and 39 nasal swab samples respectively were collected from typical pure breed representatives and unrelated animals from different SRC and BGC herds. The D-loop region was amplified as described by Achilli et al.2 and directly sequenced. The sequences were deposited in GenBank under Accession No. KF373013–KF373031 (PopSet accession no. 530540029). On the basis of the polymorphic SNP positions, seven and 12 haplotypes for the BGC and SRC sets respectively were defined (Table 1). Comments: Both investigated breeds have mitotypes similar to other Brachicerous and Podolian cattle breeds. As expected there is a low frequency of the typical African T1 haplogroup in BGC and SRC populations (5%; Table 1). Its frequency is similar among the Italian peninsula cattle populations3 suggesting African genetic influence through a Mediterranean route. The T1 haplogroup was not found in Brachicerous (Busha) and Podolian type cattle (Fig. S1, Tables S1 and S2) due to the reduction of genetic diversity, receding from the center of origin. The T2 haplogroup, except among investigated population samples (Table 1), was found also in the Greek Brachicerous4 and Podolian cattle breeds3 with similar frequencies (Fig. S1, Tables S1 and S2). The data for T1 and T2 haplogroups can be explained by the later and limited livestock introduction from Anatolia.1 As expected, the T3 haplogroup has the highest frequency. Data shown in Fig. S1 revealed that T3 haplotypes are unequally disseminated from both Podolian and Busha cattle populations.1

Conclusion: In conclusion, this study reveals high genetic diversity of the Balkan SRC and BGC breeds. SRC was presumed to be the earliest European cattle, evidenced by its mtDNA profile and supported by data for basic phenotypic characteristics of livestock from the Neolithic age to the period of the Roman Empire.5 On the contrary, BGC data confirm the later domestication and dissemination of Podolian cattle breeds.

have revealed hundreds of loci associated with economic important traits in pigs. To interpret and visualize these results, two visualization tools were developed in human genetics. However, the reference genome in LOCUSZOOM1 and an R script2 is human rather than other species, which precludes plotting a regional graph of association results for pigs. Moreover, the graphics produced by the R script lack important information, such as local linkage disequilibrium (LD) and genomic annotation (non-synonymous, synonymous, UTR, intron). Therefore, to develop a
