We know that at least three cases of ring 11 chromosome with phenotypes compatible with partial monosomy 11q have been reported. We have recently studied a 5-year-old girl referred for evaluation of growth retardation and dysmorphic features. On clinical examination, besides short stature she displayed other typical features of chromosome 11q- syndrome. Cytogenetic analysis confirmed a ring 11 chromosome. I want to know who may perform chromosome 11 specific painting probe and/or molecular studies in this patient and would be interested in a collaborative study.
