[Familial subtelomeric abnormality der(4)t(4p16.3;21q22.3) as a cause of mental retardation and mild dysmorphic features]
Abstract
A 3-year-old girl with developmental delay, dysmorphic features, hypotonia and microcephaly is presented. Fluorescence in situ hybridization (FISH) with subtelomeric probes (Multiprobe Chromoprobe T System) revealed monosomy and trisomy of subtelomeric regions 4p and 21q respectively. Clinical and pedigree data were analyzed and the phenotype -genotype correlation for partial monosomy 4p and trisomy 21q identified in the proband is also presented.
