Abstract
Microdeletion 1q21.1 (del 1q21.1) and the reciprocal microduplication 1q21.1 (dup 1q21.1) are newly recognized genomic disorders, characterized by developmental delay, dysmorphic features and congenital malformations. Congenital heart defect (CHD) is a major feature of del 1q21.1, and has been occasionally reported in dup 1q21.1. We report here a family segregating del 1q21.1 in 3 members. Two of the affected family members had CHD, including the proband with syndromic atrial septal defect, pulmonary valve stenosis (PVS), and muscular ventricular septal defects, and the maternal uncle with non-syndromic PVS. This finding prompted investigation of the role of recurrent rearrangements of chromosome 1q21.1 in the pathogenesis of PVS. We gathered 38 patients with PVS (11 syndromic and 27 non-syndromic), and searched for genomic rearrangements of 1q21.1. A dup 1q21.1 was detected in a single sporadic non-syndromic patient. Review of the CHDs in published del 1q21.1 and dup 1q21.1 subjects showed a great heterogeneity in anatomic types. In conclusion, the present family illustrates recurrent CHD in del 1q21.1, expressing either as syndromic in one family member or as non-syndromic in the another one. The spectrum of CHDs associated with del 1q21.1 and dup 1q21.1 can occasionally include PVS.
