Term Description

Trisomy 13 (T13) ordinal risk (high/low) can be determined based on dosage of chromosome specific circulating cell free (ccf) DNA in maternal plasma, the mother's current age and gestational age. The ccf DNA includes both fetal and maternal DNA. This code is based, but not limited in use to, the submitter's test, Harmony Prenatal Test, which is a non-invasive prenatal test intended to aid in the risk determination of fetal trisomy 13, 18 and 21 in women with singleton pregnancies of at least 10 weeks gestational age.

Part Description

LP99499-3   Fetal trisomy 13 risk
Trisomy 13 risk refers to the fetus's risk of having trisomy 13. The risk can be estimated based on maternal age as well as prenatal genetic testing of fetal DNA. Trisomy 13, also called Patau syndrome, is caused by the presence of three copies of chromosome 13 in each cell rather than two. Patau syndrome is associated with severe cognitive delay, various forms of congenital heart disease, brain or spinal cord abnormalities, hypotonia, cleft lip and/or palate, and poorly developed eyes. Many liveborn infants with Patau syndrome die within the first weeks of life, and less than 10% survive longer than one year. The general population risk of Trisomy 13 is about 1 in 16,000 live births, but the risk increases with increasing maternal age.

Change Reason
The system of 'Ser/Plas.maternal^fetus' was changed to 'Plas.cfDNA' (cfDNA from plasma, which includes both maternal and fetal DNA) to more precisely identify what is being measured.; Added "Fetal" to Component to clarify that the result is about the fetus.
