Tall stature and minor facial dysmorphisms in a patient with a 17.5 Mb interstitial deletion of chromosome 13 (q14.3q21.33): clinical report and review.

摘要

We present a 4-year-old boy with developmental delay and several into minor dysmorphic features due to an interstitial deletion of 17.5 Mb on the long arm of chromosome 13 [46,XY,del (13)(q14.3q21.33)]. The deletion was detected initially during routine cytogenetic screening and further analyzed on a genome-wide BAC array. In contrast to several previous papers reporting a short stature, our patient was tall with a 1 year advanced skeletal age. In this paper, we compare growth and clinical features of this patient with previously reported cases, with a similar interstitial deletion on the long arm of chromosome 13.
