Input: Context: Chediak-Higashi syndrome (CHS) is an autosomal recessive hereditary disorder in Japanese Black cattle, caused by a mutation of the Lyst gene. So far, the mutation has been detected by PCR-restriction fragment length polymorphism (PCR-RFLP) analysis. However, this method is disadvantaged by its low-throughput performance. Here, we report an alternative method involving real-time PCR with TaqMan minor groove binder probes, which shortens the total assay time by more than 120 min, analyzing 10 samples in a duplicated manner. Using this method, we examined 102 Japanese Black cattle and found that 8.8% of the cattle were CHS-carriers. These data indicate that our technique is useful for routine diagnostic testing for CHS in Japanese Black cattle.
Question: Which mutated gene causes the ChediakHigashi Syndrome?
Output:
lysosomal trafficking regulator gene
