Abstract
We report on a 28-year-old man with trisomy 7q34-qter and monosomy 15q26.3-qter caused by a paternal balanced chromosomal translocation, t(7;15)(q34;q26.3). He had bilateral congenital glaucoma (buphthalmos), as well as typical manifestations of partial trisomy 7q. To our knowledge, this is the second description of a possible relation between congenital glaucoma and 7q trisomy. He also had some Silver-Russell syndrome features, such as short stature of prenatal onset, a characteristic triangular face, clinodactyly of the fifth fingers, and body asymmetry. Fluorescence in situ hybridization analysis on his chromosomes revealed that one copy of the insulin-like growth factor 1 receptor gene (IGF1R) at 15q25-q26 was deleted, suggesting a possible role of IGF1R in the SRS phenotype.
