In brief: Spontaneous/inherite

The listed frequency of cri du chat syndrome is 1/20, 000-1/50, 000 births.
The partial deletion of chromosome 5 is thought to represent 85% by spontaneous new mutations and 15% from an abnormal chromosomal contribution from an unaffected parent that carries a balanced rearrangement of chromosomal material.
