Ctrct5 can begin with facial genetic analysis screening, through the fdna telehealth telegenetics platform, which can identify the key markers of the syndrome and outline the type of genetic testing needed. Those cells with 47 chromosomes contain an extra chromosome 21. Down syndrome was first described by an english physician john langdon down in 1866, but its association with chromosome 21 was established almost 100 years later by dr.

Snowflake cataract or snowstrom cataract. [2] infants can be asymptomatic, but may also be visually impaired from birth. Ten patients (one third) had bilateral cataract observed when first examined soon after delivery.

Our bodies are made up of millions of cells, in each cell there are 46 chromosomes, the dna in our chromosomes determines how we develop, and down syndrome occurs when there is an extra chromosome, so they have 47 chromosomes in their cells instead of 46.
