Chromosome Analysis, Routine (Solid Tissue/POC)

Test Information

Chromosome analysis is an important component in the diagnosis and evaluation of genetic disorders. Chromosome abnormalities in which there is too much or too little genetic material can result in congenital malformations, intellectual disability, and aberrant sexual differentiation. Chromosome analysis can detect chromosome abnormalities such as trisomy, monosomy, triploidy, and marker chromosomes as well as balanced and unbalanced rearrangements. For routine chromosome analysis a minimum of 20 cells are counted to determine the modal number, and a minimum of 5 cells are analyzed for chromosomal abnormalities from G-banded preparations.

Meet Ella

We will remember February 26th for the rest of our lives. On that day, we received the call from the Greenwood Genetic Center that they had discovered our daughter, Ella Marie, has Kleefstra syndrome. Very early on, my wife, Kelly, observed Ella being delayed in some of her milestones. Kelly monitored Ella’s progression and sought out testing in an effort to get Ella some assistance. Along the way, we were sent to GGC and met with Dr. Roger St...
