A 23-year-old male presented with pulmonary tuberculosis and swelling of both lower limbs. He was put on antitubercular treatment. Hemogram showed mild anemia and Pseudo Pelger-huet cells. The bone marrow (BM) examination showed 52% promyelocytes with regular round to oval nuclei, few granules and were positive for CD13 and CD33, and negative for HLA-DR. Cytogenetic analysis of the BM aspirate ...
Chromosomal segment 17q11-q21 is a commonly amplified region in human breast carcinomas. Several lines of evidence suggest that ERBB2 is the gene responsible for the emergence of this amplicon, but four novel genes (called MLN 50, MLN 51, MLN 62, and MLN 64) in 17q11-q21 have recently been found to be amplified and overexpressed in breast cancer cell lines. We investigated 98 primary breast tum...
Interstitial deletions of the long arm of chromosome 6 are relatively rare, with fewer than 100 cases reported. Phenotypic variation is in large part due to differences in size and location of the segmental aneuploidy. We report three new patients with interstitial deletions of chromosome 6q defined at the molecular level by array comparative genomic hybridization (array CGH). In two of three c...
To the Editor: Omphalocele is not an uncommon malformation; however, it usually occurs sporadically with less than a 1% recurrence risk (Winter & Baraitser 1991 ). We present recurrence of omphalocele in siblings with partial trisomy 3q and partial monosomy 1 lq as the unbalanced product of a t (3; 1 1 ) (q21;q23)mat. This was the fourth pregnancy of an unrelated couple. The mother had one heal...
Double-hit lymphomas (DHL) are defined as B-cell lymphoma with a chromosomal breakpoint affecting the MYC/8q24 locus in combination with rearrangement at (14;18)(q32;q21). We recently observed three cases of B-cell lymphoma with an extra intact MYC signal in association with the t(14;18)(q32;q21) translocation. The impact of an extra copy of MYC to the clinical course and prognosis of one patie...
