-
Molecular assay reagents intended for use in identifying the inborn (i.e., congenital) presence of three or more copies of chromosome 7 in a patient sample, rather than the normal two (i.e., trisomy 7). Individuals with trisomy 7 are usually mosaic, a condition in which normal and three-chromosome cells are present in the same person. To date, complete congenital trisomy 7 has never been reported in live-born infant.
