Özet

A patient with partial chromosome 12q duplication and 10q deletion: Chromosomal deletions and/or duplications are relatively common cytogenetic abnormalities. Clinical findings depend on pure or complex forms of the anomaly, the location and size. In those cases, using current analytical technologies increases the possibility of discovering candidate genes that were not detected by conventional karyotyping responsible for these features. Here, we report an 18-month-old girl with prenatal and postnatal growth retardation, secundum ASD and PDA, facial dysmorphic features including frontal bossing, arched eyebrows, hypertelorism, wide nasal bridge and chronic diarrhea. Chromosome analysis on the peripheral leukocytes showed a 46,XX del(10)(q26.3),dup(12)(q24.11-q24.33) do karyotype. An array-CGH analysis was performed to understand which genes were located on the deletion and duplication regions and what was their relationship with the phenotype. Based on our analyses, the deletion of the CALY gene on Chromosome 10q and the duplication of PTPN11 and TBX5 genes on chromosome 12q were possibly relevant for the clinical findings with our patient.
