Mutation origin

• Strain of Origin: C57BL/6

Mutation description

• Allele Type: Endonuclease-mediated (Humanized sequence)
• Mutation: Nucleotide substitutions
• Mutation details: Proline codon 1635 (CCT) in exon 33 was changed to leucine (CTT) (c.4904C>T, p.P1635L) using an sgRNA (targeting GCCACCAGGGAGAGATGGCGAGG) and an ssODN template with CRISPR/Cas9 technology. The mutation is the equivalent of the rare human POLR1A c.4913C>T (p.Pro1638Leu) mutation associated with craniofacial, neural, and cardiac anomalies. This allele also contains an unintended c.4895C>T (p.A1632V) mutation in cis. (J:335489)
