Chromosome 12. SCADD is caused genetically by mutations in the ACADS gene, located on chromosome 12q22-qter. [8] Mutations in the ACADS gene lead to inadequate levels of short-chain acyl-CoA dehydrogenase, which is important for breaking down short-chain fatty acids.
Chromosome 12 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 12 spans about 133 million base pairs (the building material of DNA ) and represents between 4 and 4.5 percent of the total DNA in cells .
PKS is caused by an sSMC that consists of two copies or, less commonly, four copies of the genetic material in the p arm of chromosome 12. [1] [3] Recent studies in two individuals with PKS found their sSMCs consisted specifically of genetic material located in a stretch of chromosome 12 's p arm starting at its band 11 and running to its end.

Three chromosomal abnormalities with ISCN nomenclature, with increasing complexity: (A) A tumour karyotype in a male with loss of the Y chromosome, (B) Prader–Willi Syndrome i.e. deletion in the 15q11-q12 region and (C) an arbitrary karyotype that involves a variety of autosomal and allosomal abnormalities.

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.
