Chromosome region 10q22.3–q23.3 contains several low copy repeats (LCRs) and is prone to recombination. Deletions with breakpoints within LCR3 and LCR4 have been described to be associated with intellectual disability and dysmorphic features, while the reciprocal duplications are rarely reported. We present an additional case with multiple congenital anomalies that include microcephaly, cardiac defect, and mild intellectual disability, in which a de novo interstitial 8.2‐Mb duplication of 10q22.3–q23.3, including BMPR1A and NGR3 , was identified by Illumina SNP array platform. Our study is consistent with the hypothesis that the BMPR1A is a plausible candidate gene for congenital heart disease (CHD) and should contribute to the diagnosis and treatment of these genomic diseases. © 2015 Wiley Periodicals, Inc.
