Noonan syndrome (Cappa 2024)
Height, weight, BMI and growth velocity
About this calculator
Percentiles and z-score for height, weight, BMI and growth velocity (cm/year, from two height measurements) in Noonan syndrome according to Cappa 2024 – with the LMS parameters corrected by Chou 2025, because the published values are erroneous (Expression of Concern).
In preterm infants, if a gestational age is given, age is corrected up to month 24 of life for the missing weeks up to 40+0. The z-score (SDS) describes the deviation from the median in standard deviations; the percentile the proportion of the reference population with a smaller value.
