What Is Down Syndrome Types Signs Causes Leaf Complex Care Down syndrome (also known as down's syndrome) is a chromosomal difference that occurs during foetal development. it is a genetic mutation, and although it isn't something that can be cured, medical knowledge has increased significantly over the years. if a child is born with down syndrome, receiving appropriate care and support from a young age. Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. this extra genetic material causes the developmental changes and physical features of down syndrome. down syndrome varies in severity among individuals, causing lifelong intellectual disability and developmental delays.

This type of down syndrome, trisomy 21, accounts for 95% of cases. mosaicism. mosaicism (or mosaic down syndrome) exists when there are a mixture of two types of cells, some containing the usual 46 chromosomes and some containing 47. those cells with 47 chromosomes contain an extra chromosome 21. mosaicism is the least common form of down syndrome. That said, there are certain symptoms commonly associated with down syndrome, including: short, stocky body size. a short neck. poor muscle tone with unusual flexibility. flattened facial features.
