A Case Example:
Navigating DNA Testing in Surrogacy Complexities


sleeping dad and baby

A perplexed immigration attorney contacted Vibrant Gene for information regarding a condition called chimerism (pronounced “kī-ˈmi(ə)r-izəm”; a condition where an individual has more than one complete set of DNA).


The attorney’s client, an American gentleman in his 30s, had pursued a gestational surrogacy service using his sperm and a donor egg. After carefully researching clinics, the client settled on a service located in India.  It was affordable for him and had a reputation for a high-quality service.

When the baby was born, legal DNA paternity testing indicated non-paternity. The surrogacy service insisted on no wrongdoing and contended that the baby or the client was a chimera.

The attorney was relieved to be provided with essential information regarding chimerism, Vibrant Gene also examined previous cases in literature and made key recommendations for follow-up testing. The additional DNA tests offered sufficient proof that the client and baby were not blood relatives, and found no evidence of chimerism.

The client pursued international adoption, and the attorney was able to help bring the newborn home.

This intriguing case also led to a publication co-authored by our founder, Kayla Sheets, Dan Berger (immigration attorney), Dr. Michael Baird (CSO of DNA Diagnostics Center) and Meaghan Hall.  The publication, “Navigating DNA Testing in Immigration Cases”, serves as a guide for attorneys confronted by unusual DNA test results and is available via AILA and LexisNexis.

Another chimera conundrum solved with Vibrant Gene’s services:




How is Your Paternity Testing IQ?

True or False?

1. Paternity testing is always 99.9% accurate.

(False. Genetic inconsistencies such as mutations, mosaicism and chimerism can all lead to false negative results. Other causes include not following best practices for sample collection, or human other errors.)

2. Chimeric individuals always show physical signs of having different sets of DNA.

(False. Only a small subset of chimeric individuals have two different colored eyes, patches of hair or skin tone differences.)

3. The Combined Paternity Index (CPI) is always conclusive, and definitive.

(False. When the test result is not sufficient to exclude an alleged father, some laboratories can provide a residual CPI. This result may help indicate that the true biological father is a blood relative to the tested individual.)
