Genetic Alterations

The Trpc6 gene was mutated using Crispr/Cas to introduce a mutation leading to the amino acid change E896K (glutamate to lysine substitution) in the TRPC6 protein. This corresponds to the human TRPC6 E897K mutation which can cause autosomal dominant focal segmental glomerular sclerosis. The E896K mutation is a gain-of-function mutation at the level of TRPC6 channel activity.

    Phenotype
    Gain-of-function TRPC6 mutations are a cause of autosomal dominant FSGS, a kidney disease, in humans. This mouse carries a Trpc6 point mutation inducing an E896K amino acid change corresponding to the human E897K disease mutation. This animal was generated as a potential murine model of TRPC6-induced human kidney disease.Trpc6 channel activity is enhanced by the E896K mutation. This leads to enhanced platelet phosphatidylserine exposure in vitro. The mutation does not cause significant glomerular impairment, and only minimally enhances susceptibility to glomerular injury in several models.

    Strain Development
    Two site-specific guide RNAs (PNA Bio) per locus, Cas9 nickase (PNA Bio), and a single stranded DNA oligo (IDT) carrying the desired mutant sequence were injected into FVB/NJ (Jackson Labs), and the resulting mice were screened for the presence of the desired mutation. Mice carrying the desired mutation were backcrossed with FVB/NJ (Jackson Labs) mice for at least 5 generations. Homozygous E897K/E897K mutant mice were subsequently generated and maintained through mating of homozygous animals.

    1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

    2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

    3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

    4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
