Abstract

Detection of an unbalanced t(4; 15) by FISH in a child with multiple congenital anomalies: In this report, we present the clinical history and findings in a 6-month-old male with multiple congenital anomalies, developmental delay, and an initial male karyotype with 4q+. The origin of the additional segment on 4q was unequivocally established by fluorescence in situ hybridization (FISH). Whole chromosome probe for chromosome 4 and chromosome 15-specific a-satellite probe were used. The karyotype was demonstrated to be 46,XY,der(4), t(4;15) (q35;?), inv(9)(p13q13). To the best of our knowledge the above cytogenetic abnormalities with these clinical findings have not been described previously. This case further demonstrates the advantage of FISH in the identification of anomalous chromosome regions and breakpoints.
