Overview

Also Known As:CHCHD10^S55L

This CRISPR/Cas9 generated CHCHD10^S55L mutant on the C57BL/6NJ background of the of Chchd10 gene introduces the S55L knock-in mutation. These mice may be useful in studies related to mitochondrial bioenergetics and pathogenesis of diseases such as mitochondrial myopathy, motor neuron disease, frontotemporal dementia, Parkinson's disease, and amyotrophic lateral sclerosis.

Detailed Description

CRISPR/cas9 endonuclease mediated genome editing of the Chchd10, coiled-coil-helix-coiled-coil-helix domain containing 10, gene was used to introduce the S55L knock in mutation (TCA -> TTA codon change) in exon 2. The mouse S55L mutation is equivalent to the human S59L mutation. The targeted Chchd10 gene encodes a mitochondrial intermembrane protein that is involved with mitochondrial cristae morphology and oxidative phosphorylation. Mutations in the human CHCHD10 gene can cause frontotemporal dementia and amyotrophic lateral sclerosis (ALS). Chchd10^S55L heterozygous mice have a shortened mean lifespan of approximately 344 days. Onset of body weight loss and progressive kyphosis is approximately 200 days of age in female heterozygotes and 125 days in male heterozygotes. Homozygotes exhibit a more severe body weight loss compared to heterozygotes. Muscle weakness is apparent at approximately 150 days of age with exercise intolerance, with evident muscle mass loss at 330 days of age. At approximately 260 days of age, heterozygotes exhibit motor deficit (forelimb grip strength) which progresses to abnormal gait. Hypertrophic cardiomyopathy is detected in heterozygotes at 330 days of age. Pregnant female heterozygotes exhibit accelerated mortality compared to virgin female heterozygotes. Histological analysis of heart tissue from breeding heterozygous females reveals cytoplasmic vacuoles, increased variation of the size of the nucleus, and fibrotic interstitial collagen accumulation. Cardiomyocyte ultrastructure is altered (increased number of mitochondria with abnormal features). The myofibers from gastrocnemius muscle exhibit splitting, increased number of atropic and angular fibers, increased nuclear density and central nuclei. Disorganized sarcomeres and increased number of abnormal mitochondria are also observed. Neuromuscular junction innervation and morphology is degenerated and abnormal: approximately 50% of neuromuscular junctions in Chchd10^S55L muscle show no innervation.

Development

The Chchd10 ^G56S allele was created by Dr. Cathleen Lutz (The Jackson Laboratory) using CRISPR/cas9 endonuclease-mediated genome editing in C57BL/6NJ mouse zygotes (Stock No. 005304).
Specifically, the coiled-coil-helix-coiled-coil-helix domain containing 10 locus (Chchd10) on chromosome 10 was targeted with single guide RNAs designed to substitute the TCA wild type serine codon with a TTA leucine codon (S55L) in exon 2.
The sgRNAs, an oligonucleotide sequence containing the S55L mutation, and cas9 endonuclease were electroporated into the cytoplasm of single cell C57BL/6NJ-derived zygotes containing well recognized pronuclei. Embryos were transferred to pseudopregnant females, and correctly targeted pups (identified by DNA sequencing) were bred to C57BL/6NJ (Stock# 005304) for germline transmission. Mice derived from founder 54 (GET473) were further bred to C57BL/6NJ inbred mice for 2 generations to develop the colony.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
