    Abstract:
    Interstitial deletions of the long arm of chromosome 3 are rare and detailed genotype-phenotype correlations are not well established. We report on the clinical, cytogenetic and molecular findings of a 5-year-old patient with a de novo interstitial deletion from 3q25.1 to 3q25.32. Clinical features include relative microcephaly, developmental delay and facial dysmorphism with a coarse face, ptosis, synophrys, epicanthic folds, broad nasal bridge, long philtrum, large mouth with full lips, dysplastic and low-set ears. Revealed by conventional banding techniques, the deleted region of 8.9 Mb was confirmed by fluorescent in situ hybridization (FISH) analyses and array comparative genomic hybridization (array-CGH). To our knowledge, this is the smallest interstitial deletion reported in the 3q25 region. The phenotype of our patient is compared with the 10 previously reported cases implicating the 3q25 region.
