Abstract
Bovine isoleucyl-tRNA synthetase (IARS) disorder, a major cause of weak calf syndrome, is
caused by a homozygous missense (c.235G>C) mutation in the bovine IARS
gene of Japanese Black (JB) cattle, which was identified in 2013. However, the extent to
which the carrier rate has changed at Kagoshima prefecture, Japan, and whether the carrier
status is associated with any clinical or reproductive problems, have yet to be
ascertained. In this study, using a real-time polymerase chain reaction-based genotyping
assay, we determined the carrier rate in a regional JB cow population at Kagoshima
prefecture. Comparative analyses were performed on the metabolic profile test (MPT)
results and reproductive performance data obtained for heterozygous carrier and homozygous
wild-type cows. In 2009 and 2018, DNA samples were collected from 130 and 462 clinically
healthy JB cows, respectively, in Kagoshima prefecture. MPT results and reproductive
performance data were evaluated for 62 cows, comprising four heterozygous carriers and 58
wild-type cows. Genotyping revealed that the carrier rate was 6.9% in 2009 and 1.5% in
2018, the difference of which was statistically significant (P<0.005).
There were no statistically significant differences between the carrier and wild-type cows
with respect to either MPT results or reproductive performance, indicating that the
carrier cows have necessary IARS activity to maintain minimal health and reproductive
potential.

Abstract
A case of lysosomal storage disease has been reported in a calf of Japanese Black cattle. Lysosomal storage diseases are hereditary diseases caused by deficiency of lysosomal hydrolases. The clinical and pathological features and accumulated substrates of the affected animal indicated a possibility of sialidosis or galactosialidosis caused by deficiency of neuraminidase (NEU1) or protective protein for beta-galactosidase (PPGB). In the present study, we investigated nucleotide sequences of the genes encoding these two proteins to evaluate whether mutation of these genes is involved in this disease. We determined cattle genomic sequences of these two genes by using bovine EST sequences and the nucleotide sequences of all exons of these genes were compared between affected and normal animals. The results showed several nucleotide substitutions, but none of them was a functional mutation or specific to the affected animal. Furthermore, genotyping of the microsatellite markers in the vicinity of these two genes revealed no homozygosity of the chromosomal regions including these genes in the affected animal. These findings indicated that neither NEU1 nor PPGB gene is responsible for the lysosomal storage disease of Japanese Black cattle and therefore the disease is neither sialidosis nor galactosialidosis.
