Structural Abnormalities

A male infant with failure to thrive was found to have a previously unreported combination of chromosomal structural abnormalities. Evidence is presented which characterizes the abnormal chromosomes as a late-replicating G ring and a pericentric inversion in an early replicating B group chromosome. The mechanisms of pericentric inversion and ring formation are discussed, and possible genetic consequences are noted. The patient's phenotype differed significantly from that of previously reported subjects with G rings, G deletions, and structural abnormalities of the B group. This phenotypic difference could be attributed to the apparent fact that the proband's G ring was a late replicator (G1) and earlier cases were not, on to the seeming variability in ring size which suggested partial trisomy/partial monosomy, or perhaps to the probability that the abnormal B chromosome was pericentrically inverted rather than deleted. The question of the etiologic significance of broken parental chromosomes must be raised, although more study is needed in the area of chromosome breakage, its relationship to abnormal progeny, and the possible role of environmental agents, e.g., drugs and irradiation.

We report a 36-year-old Caucasian male identified with distal partial trisomy 15q and partial monosomy 16p from an unbalanced chromosome translocation detected by microarray and FISH analysis. He had a history of developmental delay and intellectual disability, chronic anemia, tall and slender stature, thoracic scoliosis and lumbar lordosis, and dysmorphic features. The distal partial trisomy 15q included the insulin-like growth factor 1 receptor gene involved with growth, while genes in the distal partial monosomy 16p region are involved with alpha hemoglobin production, intellectual disability, dysmorphic features, and acromegaly. The chromosome derivative found in our patient contains genes known to play a role in his phenotype.

Two fourth cousins with a strikingly similar pattern of malformation and who have an unbalanced translocation (46, XY, —17, +t (17p; lOq) are described. From an analysis of the phenotypes of these patients and others reported with lOq trisomy, we propose that the trisomy 1Oq 24-26 syndrome includes: growth and mental retardation, a characteristic facies (microcephaly, flat face with spacious forehead, small nose, depressed nasal bridge, arched wide-spaced eyebrows, blepharophimosis, microphthamia, low-set ears, bow-shaped mouth with prominent upper lip, micrognathia), palate anomalies (high-arched cleft or agenesis), congenital heart disease, and anomalies of the hands and feet. Anomalies common to the cousins, but not described in other patients with trisomy 1Oq, are believed to be expressions of a partial monosomy of 17p.
