Natera announced results of a prospective validation study published in the Journal of Clinical Medicine demonstrating 100% accuracy of its Panorama non-invasive prenatal test in determining zygosity
, fetal sex, and chromosomal abnormalities in twins as early as 9 weeks of gestation.
BCG reaction in twin newborns: effect of zygosity
We could not test the apparently unaffected members of the family and therefore cannot comment upon the zygosity
of the genetic mutations.
Powered by Asuragen's proprietary AmplideX technology, the assay's robust, two-primer design addresses sample zygosity
and preserves the CAG repeat profile even in the presence of adjacent SNPs.

The Natera[R] Panorama[R] noninvasive prenatal test (NIPT) now screens twin pregnancies for zygosity
and chromosomal abnormalities.
Operationalization, assessment method, zygosity
determination method, and age were significant moderators of the magnitude of genetic and environmental influences on antisocial behaviour, but there were no significant differences in the magnitude of genetic and environmental influences for males and females.
