Human epidermal growth factor receptor 2 (HER2) and topoisomerase II alpha (TOP2A) genes have been proposed as predictive biomarkers of sensitivity to anthracycline chemotherapy. Recently, chromosome 17 centromere enumeration probe (CEP17) duplication has also been associated with increased responsiveness to anthracyclines. However, reports are conflicting and none of these tumor markers can ye...

Gastrointestinal duplications are uncommon congenital abnormality in 80% of cases and manifest before the age of 2. Ileal duplication is the most common while colonic duplication, either cystic or tubular, occurs in 10-15% of cases and remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients, colonic duplication is encountered in adults only in a few cases. The...

Gene duplication is thought to play the singular most important role in the formation of novel genes. The canonical model of gene duplication postulates that novel genes arise in a two-step fashion, namely, (1) the complete duplication of a gene followed by (2) the gradual accumulation of mutations in one or both copies leading to an altered function. It was previously demonstrated that more th...

Acute myeloid leukemia is a hematopoietic stem cell neoplastic disease associated with high morbidity and mortality. The presence of FLT3 internal tandem duplication mutations leads to high rates of relapse and decreased overall survival. Patients with FLT3 internal tandem duplication are normally treated with hematopoietic stem cell transplantation in first complete remission. Nevertheless, th...

Enteric duplication cyst is one of the rarest forms of cystic lesion of the pancreas. We report a unique case of an enteric duplication cyst of the pancreas that was communicating with a duplicated pancreatic duct. A 7-year-old girl with severe acute abdominal pain was found to have a large cyst that was smoothly communicating with the dilated pancreatic duct in the pancreatic tail. Analysis of...

BACKGROUND Penile duplication (diphallus) is an extremely rare disorder. It is almost always associated with other malformations like double bladder, exstrophy of the cloacae, imperforate anus, duplication of the rectosigmoid and vertebral deformities. Meanwhile anal canal duplication, the most distal and least common duplication of the digestive tube and is a very rare congenital malformation....

introduction: about half of acute myeloid leukemia (aml) adult patients have no cytogenetic abnormalities as a main determinant of complete remission after treatment, so other markers are needed such as flt3-itd (fms-like tyrosine kinase3-internal tandem duplication) mutations in patients with normal karyotype. the objective of this study was assessing the frequency of flt3-itd mutations and it...

De novo duplication of 2q is very rare. Most cases of 2q duplications result from familial translocations, and are associated with simultaneous monosomy of another chromosome segment. To our knowledge and search in English literature there are less than 20 reported cases of isolated 2q duplication. Hereby we introduce a 4.5-year-old Iranian boy of a non-consanguineous marriage who was referred ...

Early in female embryonic development the uterus, oviduct, and vagina arise from paired line. Müllerian duct anomalies (MDAs) result from defects in fusion or incomplete resorption. Failure of resorption of the median septum results in a septate or subseptate uterus. Complete or partial duplication of the uterine cavities depends on whether the failure of resorption is complete or partial (1).
