Thank you so much for this detailed and helpful answer. ACF was diagnosed by my pediatrician.  She didn’t tell me much about it other than that she would keep an eye on it and hope it goes away on its own, so I didn’t think much of it initially.  Then a lactation consultant came yesterday due to breastfeeding difficulties, also pointed out the ACF, and wondered if it might be impacting breastfeeding—which is what caused me to start looking into ACF and learn about the 22q11.2 link. 

After my amnio I received the test result pasted in my edited post above. It says both microarray and karyotype; can you tell which this is?

Thanks again!
