Dwarf cats often suffer from spinal disorders, such as lordosis (excessive curvature of the spine) and pectus excavatum (hollowed chest). [7] As with human dwarfism, there are still a lot of unknown mysteries in the science behind feline dwarfism. It is found that achondroplasia in humans is the result of the FGFR3 gene.
The domesticated cat and its closest wild ancestor are both diploid organisms that possess 38 chromosomes [2] and roughly 20,000 genes. [3] About 250 heritable genetic disorders have been identified in cats, many similar to human inborn errors. [4]
A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder is a missing, extra, or irregular portion of chromosomal DNA. [ 1 ] [ 2 ] These can occur in the form of numerical abnormalities, where there is an atypical number of chromosomes, or as structural abnormalities, where one or ...
Chromosomal Deletion Cri du chat syndrome is a rare genetic disorder due to a partial chromosome deletion on chromosome 5 . [ 1 ] Its name is a French term ("cat-cry" or " call of the cat ") referring to the characteristic cat-like cry of affected children (sound sample [1] ). [ 2 ]
The researchers tested the salty colored cats and 178 normal-colored samples from the biobank for the new gene variant. Each of the five salmiak cats had two copies of the recessive gene.
MLPA is a test that finds and records DNA copy change numbers through the use of PCR. MLPA can be used to detect tumours in the glial cells of the brain, as well as chromosomal abnormalities. [ 8 ] Array-based comparative genomic hybridization (aCGH) tracks chromosome deletions and or amplifications using fluorescent dyes on genomic sequences ...

A small supernumerary marker chromosome (sSMC) is an abnormal extra chromosome.It contains copies of parts of one or more normal chromosomes and like normal chromosomes is located in the cell's nucleus, is replicated and distributed into each daughter cell during cell division, and typically has genes which may be expressed.
