"We've done genetic testing and can basically rule it out. We are also very clear about the genetic lineage from his grandfather's side. It should be a rare Y chromosome-linked inheritance, which cannot be passed down to him, so we have ruled out genetic diseases."
Director Xu specifically looked up the hereditary pedigree chart from the case records and asked the child's mother again, "You're sure about these affected relatives, right?"
"I won't get it wrong," his mother was very certain.
Moreover, his mother's family was good enough to photograph the medical records they could find and send them over via WeChat, so the genetic lineage isn't problematic and is quite reliable.
"You see, this fully aligns with the characteristics of Y chromosome-linked inheritance. How could it possibly be passed down to this child?" Director Xu pointed out to Yang Ping.
Indeed, if the genetic lineage is correct, the grandfather's disease couldn't have been inherited by the grandson.
