Translocations are the most common structural abnormality in the human genome. Carriers of balanced chromosome rearrangements exhibit increased risk of abortion or a chromosomally-unbalanced child. The present study was carried out in 2017 at the Iranian Blood Transfusion Research Center. This study reported a rare chromosomal disorder with 4p duplication and 10q distal deletion syndrome which is associated with various complications at birth. Defects included the following characteristics: dysmorphic facial characteristic, hand or foot anomalies, growth retardation, developmental delay, strabismus, heart defects and renal anomalies. Cytogenetic analysis and array CGH were performed and, for the first time, we reported a patient with trisomy 4p16.3p12 and monosomy 10q26.3. The patient was found to have: arr 4p16.3p12 (37,152-45,490,207) x3, 10q26.3 (134,872,562-135,434,149) x1 genomic imbalances.

Cytogenetic investigation in Iranian patients suspected with Fanconi anemia.

J Pediatr Hematol Oncol 2006 Dec;28(12):834-6

Research Centre of Iranian Blood Transfusion Organization, Hemmat Avenue, Tehran, Iran.

We present our study on 318 patients suspected with Fanconi anemia (FA) referred to The Iranian Blood Transfusion Organization during the period of 4 years. Mitomycin C (MMC) was used as a DNA cross-linker to study chromosomal breakage. In total 61 positive cases were diagnosed cytogenetically. The ratio of women being affected was slightly higher than men. Comparison of several hematologic and clinical parameters in FA (MMC positive) and non-FA (MMC negative) patients showed no clinically significant differences. This study also indicates that this sort of test is very useful and essential for accurate diagnosis of patients with FA with or without congenital anomalies.
