Resumo

Background: Partial duplication 1q is a rare cytogenetic anomaly frequently associated to deletion of another chromosome, making it difficult to define the precise contribution of the different specific chromosomal segments to the clinical phenotype. Case presentation: We report a clinical and cytogenomic study of a patient with multiple congenital anomalies, heart defect, neuromotor development delay, intellectual disability, who presents partial trisomy 1q32 and partial monosomy 11q25 inherited from a paternal balanced translocation identified by chromosome microarray and fluorescence in situ hybridization. Conclusion: Compared to patients from the literature, the patient's phenotype is more compatible to the 1q32 duplication's clinical phenotype, although some clinical features may also be associated to the deleted segment on chromosome 11. This is the smallest 11q terminal deletion ever reported and the first association between 1q32.3 duplication and 11q25 deletion in the literature. (AU)
