The 99 Lives Cat Genome Sequencing Initiative continues to expand in participants and cat genomes! Approximately 40 different research institutions, zoological parks, pet food companies and animal health companies are contributing to the 99 Lives Project. We have genomes from over 200 domestic cats now – twice the original 99 Lives goal! Many wild felid genomes are included as well.
The Feline Genetics & Comparative Medicine Laboratory at MU has submitted ~117 domestic cats for whole genome sequencing, as MU-specific projects and in collaborations with the 99 Lives Consortium. These cats represent 59 different genetic health and trait projects. Four different wild felid species have been submitted as well, encompassing five different health projects. Several studies have been published including an example of performing Precision Medicine in cats!1-5. Twenty-eight of 59 domestic cat projects (47%) are highly likely to be solved! Several unsolved projects will need additional cat genome sequencing for complex diseases such as asthma, feline oral facial pain, fibrosarcoma, wool sucking behavior, FIP susceptibility/resistance, amyloidosis in Siamese and cytauxzoonosis susceptibility/resistance.
99 Lives has proven success – help keep us rolling and get our manuscripts published! Donate and participate when you can – start new projects!

The DNA variants have been identified for 14 additional projects and we are continuing to produce the data and information required for publications, including;
- Bengal Progressive Retinal Atrophy
- Chediak-Higashi Syndrome
- 3 forms of methemoglobinopathy
- Lykoi hair coat – 4 variants
- 2 forms of Ehlers- Danlos Syndrome (stretchy skin)
- 1 form of multiple systems degeneration
- 1 form of a neurological / skeletal disorder
- Risk variants for Abyssinian amyloidosis
- Risk variants for feline spontaneous epilepsy
Most recent analyses has led to the identification of several candidate genes and DNA variants for five (5) breed-specific traits that still need to be validated, including,
- Korats with persistent dilated pupils
- Siberians with hypertrophic cardiomyopathy
- Ragdolls with a missing uterine horn / kidney
- Egyptian Maus with urate stones
- LaPerm hair coat
Collaborators have identified at least four different DNA variants for cat diseases and traits as well.
