title: A female infant with duplication of chromosome 2q33 to 2q37.3.
abstract: We report a 13-month-old female child with a de-novo inverted duplication of chromosome 2q extending from 2q33 to 2q37.3. She had microcephaly and craniofacial dysmorphism compatible with previously reported cases with overlapping duplications of chromosome 2q. Although a facial phenotype for pure partial trisomy 2q3 has been described, some controversy still exists regarding possible band specificity for the facial findings. We consider this child provides further evidence for a recognizable facial appearance associated with duplication of chromosome band 2q33 to 2q37.3. Other clinical features found with duplication for chromosome 2q3 have been variable and we provide a summary of the findings in previously reported cases.
