Centric fission of chromosome No. 4 was found in the healthy mother of two children with trisomy 4p. The two telocentrics derived are stable and show no evidence of fusing again. The 2:3 ratio of unbalanced offsprings born to the proposita indicates that, contrary to the evidence emerging from studi

A centric fission of chromosome 9 was found in a boy with trisomy 9p resulting from a de novo del (9p) and a 9p isochromosome. The patient presented with clinical findings similar to those described in previously reported cases of trisomy 9p. The cytogenetic evaluation and the molecular analysis usi
We observed a paracentric inversion of 19p in a 15-month-old white boy with developmental delay and mild facial anomalies. The inversion of 19p was also present in his phenotypically normal mother and maternal grandfather.
Chromosome studies were carried out on three patients for the following reasons: (1) growth retardation and mental subnormality in a boy; (2) marked developmental delay in a female infant; (3) routine check on a man whose wife had a stillborn with congenital anomalies. An interstitial deletion at 7q
