Which condition has a specific growth chart due to different growth patterns?

Trisomy 21, commonly known as Down syndrome, has a specific growth chart due to the unique growth patterns observed in individuals with this condition. Children with Down syndrome typically have different physical growth trajectories compared to their peers, especially in terms of height, weight, and head circumference. As such, using standard growth charts may not accurately reflect their growth and development, making it essential to utilize specialized growth charts designed for this population. The availability of these tailored growth charts helps healthcare providers monitor the growth of children with Down syndrome more effectively, ensuring that their developmental needs are adequately met and that any concerns regarding their growth can be identified and addressed promptly.

In contrast, the other conditions listed do not necessarily require separate growth charts, as their growth patterns may not deviate significantly enough from general population norms to warrant such differentiation.
