downregulated in ALS muscle and C9-ALS motor neurons; unchanged in ALS spinal cord; increased in ALS frontal cortex
hsa_circ_0056856 is downregulated in ALS skeletal muscle together with decreased ITGB6 mRNA; it is decreased in C9-ALS motor neurons, unchanged in ALS spinal cord, and increased in ALS frontal cortex. No mechanism was established.
