Chromosomal Abnormalities: Genetic Disease Burden in India
نویسندگان
چکیده
Chromosomal abnormalities are frequent events. Globally, at least 7.6 million children are born annually with severe genetic or congenital malformations. Precise prevalence data are difficult to collect, especially in India, owing to great diversity of conditions and also because many cases remain undiagnosed. Genetic and congenital abnormality is the second most common cause of infant and childhood mortality and occurs with a prevalence of 2560 per 1000 births. The higher prevalence of genetic diseases in a particular community may, however, be due to some social or cultural factors.

Chromosomal Analysis of Couples with Repeated Spontaneous Abortions in Northeastern Iran
Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs). The aim of this study was to detect chromosome abnormalities in couples with RSAs and to compare our results with those reported previously. Materia...
متن کاملCytogenetic and FMS-Like Tyrosine Kinase 3 Mutation Analyses in Acute Promyelocytic Leukemia Patients
Background: The secondary genetic changes other than the promyelocytic leukemia-retinoic acid receptor (PML-RARA) fusion gene may contribute to the acute promyelocytic leukemogenesis. Chromosomal alterations and mutation of FLT3 (FMS-like tyrosine kinase 3) tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia. However, the prognostic significance of FLT3 mutat...
متن کاملInm-8: Assisted Reproductive Technologies and Genetics
Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...

متن کاملRole of SOX9 in the Etiology of Pierre-Robin Syndrome
Objective(s:Cleft lip/palate are common congenital anomalies, affecting approximately 2/1000 live births. Pierre Robin Sequence is a subgroup of the cleft palate population. Chromosomal abnormalities near the SOX9 gene disrupt the regulation of this gene and prevent the SOX9 protein from properly controlling the development of facial structures, which leads to isolated PRS. The present study wa...
