We have so far sequenced three cat families where “midline defect” occurs in the offspring. In these three families there were 5 affected kittens, their parents and a healthy sibling. We have also sequenced a further 16 unrelated healthy control animals. In two of the families, the defective kittens look more alike, while the third family has several special features.
Our preliminary analyzes suggest that several genomic regions may be involved in the development of the midline defect. But this result could also be due to the fact that we currently have too few animals to compare. However, one chromosomal region overlapped between the families with more different defects, which is positive.
Therefore, we plan to collect more sick and healthy cats to try to get a clearer genetic picture. So far, we have analyzed too limited material to be able to draw any firm conclusions.
We also plan to autopsie some of the kittens to try to find out if they carry hidden defects inside their bodies. This can help classify the kittens and can in turn lead to clearer genetic results.
Hope more cat owners get in touch about samples for sequencing so we can solve the mystery of what causes this very problematic genetic defect.
