Chromosomal microdeletions, which cannot be detected by traditional karyotype analysis, may cause abnormalities in the next generation, such as Prader-Willi syndrome and Williams syndrome. These conditions are often accompanied by not only physical abnormalities but also intellectual disabilities and developmental delays.

Chromosome microarray testing cannot completely replace traditional karyotyping; it should be considered as a supplementary tool to traditional methods, providing expectant parents with more detailed and comprehensive information about their baby's health.

Chromosome microarray testing is quite simple; it only requires an additional 10cc of the sample to be taken during the amniocentesis, without increasing the risk of the procedure.

It is necessary for young pregnant women to undergo amniocentesis as well! The likelihood of fetal chromosomal microdeletions is not related to the age of the pregnant woman. For instance, 80% of babies with Down syndrome are born to mothers under the age of 34. Therefore, it is recommended that mothers of any age consider amniocentesis.

If the test results show abnormalities, please consult further with your primary care physician and a genetic specialist.

Normal test results do not guarantee that the baby is completely healthy, as all tests have limitations and cannot diagnose 100% of genetic disorders. However, it is undeniable that chromosome microarray testing can identify more causes of illness compared to traditional methods.
