FISH results of cells from the patient and his parents. Two copies of 1q42 were detected in the father (a) and mother (b), while only 1 copy of 1q42 was retained in the cells of the patient (c), thus identifying the deleted region at 1q42. The red fluorescence of 1q42 was indicated with a white arrowhead
