familial short stature
Inherited pattern of short stature where children have height consistent with their parents' genetic potential.
Full Definition
Familial short stature (FSS) refers to a pattern of growth where children are short due to genetic factors inherited from their parents, rather than any underlying pathological condition. Children with FSS typically have parents who are also short, and the child's height falls within the expected range based on parental heights (target height or mid-parental height). These children usually have normal growth velocity, appropriate bone age for chronological age, and normal endocrine function. Their short stature represents the lower end of the normal distribution of human height. Unlike pathological causes of short stature, children with FSS are healthy and do not require medical intervention. However, distinguishing FSS from other causes of short stature requires careful evaluation to exclude treatable conditions.
Usage
Usage note: Calculate mid-parental height to support this diagnosis; distinguish from pathological causes.
