Area of Science:

  • Genetics
  • Ophthalmology
  • Molecular Biology

Background:

  • Mutations in the MFRP gene cause various ocular diseases.
  • Autosomal recessive retinitis pigmentosa (arRP) with nanophthalmos is linked to MFRP gene mutations.
  • Patient presented with unique retinal pigmentary changes.

Purpose of the Study:

  • To develop a gene editing strategy for the Mfrprd6 mouse model.
  • To install the specific Mfrprd6 c.445+3_6AAGTdel mutation in Neuro-2a cells.
  • To facilitate screening of gene editing correction approaches for MFRP-associated retinal diseases.

Main Methods:

  • Developed a prime editing strategy.
  • Targeted the Mfrprd6 c.445+3_6AAGTdel mutation.
  • Utilized the Neuro-2a (N2a) mouse neuroblastoma cell line.

Main Results:

  • Successfully developed a prime editing strategy.
  • Demonstrated the installation of the Mfrprd6 c.445+3_6AAGTdel mutation in N2a cells.
  • Established a method for screening gene editing approaches.

Conclusions:

  • Prime editing provides a viable strategy for introducing specific mutations in cell lines.
  • This method is crucial for advancing research into MFRP-associated ocular diseases.
  • Facilitates the development and testing of gene therapies for retinitis pigmentosa.
