Abstract

Small hands and feet (acromicria) are often cited as manifestations in the Prader-Willi syndrome (PWS), but it has been our experience that these are not universal findings. To address this issue, we obtained longitudinal and cross-sectional data, retrospectively and prospectively, including height, hand length, and foot length, on 56 patients with PWS who are followed in the multidisciplinary PWS clinic at the University of Connecticut Health Center. Hand and foot lengths were plotted using two published sets of normative data. In addition, height age was calculated on each measurement of stature so that the corresponding hand and foot measurements could be compared to those expected for height, rather than age, as many PWS individuals are short. Foot length was proportionately smaller than hand length in all individuals; this difference was more striking in females. By age 12 years, almost all individuals had a foot length less than 25th centile for chronological age and less than 50th centile for height age. Female hand length was also less than 25th centile for chronological by age 12 years and less than 50th centile for height age in almost all cases. Male hand length data appeared to fall more within the normal range until adulthood, although fewer data were available. Black individuals with PWS had relatively larger hands and feet than their Caucasian counterparts. Many people with PWS had hand and foot lengths which fell within the normal range, particularly those under the age of 12 years and those whose height was greater than 50th centile for age.(ABSTRACT TRUNCATED AT 250 WORDS)
