摘要：

Deletions in the 10q22.3q23.2 region are rare and mediated by 2 low-copy repeats (LCRs 3 and 4). These deletions have already been recognized as the 10q22q23 deletion syndrome. The phenotype associated with this condition is rather uncharacteristic, and most common features are craniofacial dysmorphisms and developmental delay. We describe a boy with craniofacial dysmorphic features, developmental delay, tetralogy of Fallot, hand/foot abnormalities, and recurrent respiratory tract infections. Chromosomal microarray analysis disclosed a 7.8-Mb microdeletion at 10q22.3q23.2, flanked by LCRs 3/4, and an additional 16q12.1 microdeletion of 189 kb. This article reviews the clinical signs of reported cases with similar deletions and compares them with our patient, contributing to a better understanding of genotype-phenotype correlation.
