Down Syndrome

Genetics The presence of a complete or partial third copy of human chromosome 21 (Hsa21) is the cause of DS. Partial copy should include all or part of the long arm of Hsa21.This excess of genetic material leads to a dysregulated expression of certain genes. The functional impact of these changes could be a direct result of the action of the proteins expressed in excess by the Hsa21 genes, or i...

Down Syndrome

Down syndrome is characterized by a series of minor anomalies that eachoccurwitha frequencyofabout50– 80% and will not, therefore, be present in all persons with Down syndrome.
