Methylene tetrahydrofolate reductase (MTHFR) plays a significant role in the metabolism of methionine. MTHFR deficiency is an autosomal recessive trait that could be a significant risk factor for a number of defects, for example, vascular events, due to lower dietary folate intake among South Indians. To find the incidence of 677 C>T and 1298 A>C in MTHFR(More)
Karyotyping was done in 100 children suspected of having chromosomal abnormalities of genetically uncertain syndromes, multiple congenital anomalies, short stature, dysmorphic features, unclassified mental retardation, and Down syndrome. A total of 56 patients had an abnormal karyotype: ring chromosome of 13 was seen in 1 patient (1.78%), and trisomy 21 was(More)
BACKGROUND & OBJECTIVES Fluorescence in situ hybridization (FISH) is increasingly being recognized as the most accurate and predictive test for HER 2/neu gene amplification and response to therapy in breast cancer. In the present study we investigated HER-2/neu gene amplification by FISH in breast carcinoma tissue specimens and compared the results with(More)
The mixed lineage leukemia (MLL) gene at chromosome band 11q23 is commonly involved in reciprocal translocations that is detected in acute leukemia. The MLL gene, commonly known as mixed lineage leukemia or myeloid lymphoid leukemia, has been independently identified and cloned from the 11q23 breakpoint of acute leukemia. We describe a patient with acute(More)
Primary amenorrhea refers to absence of spontaneous menarche even after the age of 16. Cytogenetic analysis in two cases with primary amenorrhea, short stature, poorly developed secondary sexual characteristics, and growth retardation were studied. Routine GTG-band analysis of metaphases from peripheral blood leucocytes revealed female karyotype with a(More)
Human metapneumovirus (HMPV) and human respiratory syncytial virus (HRSV) are ubiquitous respiratory viral pathogens. They belong to the family Paramyxoviridae (subfamily Pneumovirinae) and is responsible for acute respiratory tract infections in children, elderly and immunocompromised patients. We designed and tested a multiplex reverse transcriptase(More)
