Monosomy 5p and trisomy 12p in a boy with familial balanced translocation
Vasudevan PC., Parker MJ.
We report on a boy with monosomy 5p involving the Cri-du-Chat critical region and trisomy 12p detected by subtelomere study. Familial studies showed that the boy's mother and paternal grandfather had a balanced reciprocal translocation between the short arm of chromosomes 5 and 12. The boy had an overlap of features of both chromosomal conditions, even though the Cri-du-Chat phenotype was more prominent. © 2006 Lippincott Williams & Wilkins.
