The entire coding sequence of the Rcc1 locus has been deleted and replaced with sequence that encodes the Hsap\RCC1 coding sequence that has been mutated to carry a G43S amino acid substitution (a putative pathogenic variant identified in patients with acute-onset axonal neuropathy following infection), and which is tagged at the N-terminal end with mScarlet-I (allowing expression of the tagged Hsap\RCC1 protein under the control of Rcc1 regulatory sequences). A Avic\GFP3xP3.cUa marker has also been inserted, downstream of the Hsap\RCC1 coding sequence.
