Our genes help make up the blueprint for who we are. They help determine what we look like, how large we grow, how smart we are, and even how we think. They are generally handed down from our parents, meaning that parents and their children tend to share a lot of similarities with each other.
This blueprint includes chromosomes which determine our sex. Women usually have two X chromosomes, while men usually have one Y and one X chromosome. Men with Klinefelter syndrome, however, have two X chromosomes and one Y chromosome.
Those that are lucky will show barely any symptoms at all, while some can have symptoms that have a significant impact on their lives.
Symptom #1: Slow Developing
Different babies develop at different rates. Sitting up and standing come at different times to babies and it doesn’t necessarily mean that there is a problem. Usually, even those that are a bit slower than the others will catch up with the rest at some point.
Despite this, however, slower than usual developing can be a sign of Klinefelter syndrome. It might not be noticeable to begin with because babies do develop at different rates. In addition to sitting and standing, it can also cause babies to develop slower than others when it comes to speech. If you do notice a baby is developing slower than they should do, you should arrange to get it checked out.
