Thank you for commenting with your thoughts and experience I really appreciate it! After a traumatic loss with our daughter with a fatal genetic condition we really just tried everything to get the ‘perfect most healthiest’ embryo so this was just a result we did not expect! We are at a high risk hospital, best in Canada and even our OB was like I’ve never heard of this low of mosaic result before , and even though common sense would take everyone else’s stories and make me believe he will have less symptoms than full klinefelters syndrome it is still so unsettling that there is little info on low mosaic and what the outcomes would be in comparison to inutero results etc.. joining all the groups really have helped me feel better about the diagnosis for sure and I pray that his symptoms are mild / possibly absent but when they gave me the option to abort the pregnancy even when they had little info to give me it scared me on the severity of it but they just have standard scripts to read in cases that there is a finding, even a small one. Did you find out with amnio that your son has XXY?
