Associations between attention deficit hyperactivity disorder (ADHD) and genetic polymorphisms in the dopamine receptors, transporter and metabolizing enzymes have been reported in different ethnic groups. Gene variants may affect disease outcome by acting synergistically or antagonistically and thus their combined effect becomes an important aspect to(More)
Autism is a neurodevelopmental disorder with early manifestation. It is a multifactorial disorder and several susceptible chromosomal regions for autism are identified through genome scan studies. The gene coding for glutamate receptor 6 (GluR6 or GRIK2) has been suggested as a candidate gene for autism based on its localization in the autism specific(More)
Serotonin transporter (SLC6A4) polymorphisms are variously implicated in mediating susceptibility to attention-deficit-hyperactivity disorder (ADHD), a highly heritable and heterogeneous disorder with onset in childhood. Since there has been no survey in this regard from India, a sample of 56 ADHD cases and 174 healthy individuals from Kolkata were(More)
Synaptosomal-associated protein 25 (SNAP25) is an essential component for synaptic vesicle mediated release of neurotransmitters. Deficiencies or abnormal structure or function of SNAP25 protein, possibly arising through genetic variations in the relevant DNA code, has been suggested to play role in the pathology of several neurobehavioural disorders(More)
Serotoninergic dysfunction is highly implicated in autism. Serotonin transporter gene (SLC6A4) that regulates synaptic serotonin level has been investigated as a candidate gene for autism, but consensus opinion on possible association is still lacking. Converging evidences of platelet-hyperserotoninemia in approximately 25% of the patients, betterment of(More)
Autism is a neurodevelopmental disorder with high heritability factor and the reelin gene, which codes for an extracellular matrix protein involved with neuronal migration and lamination is being investigated as a positional and functional candidate gene for autism. It is located on chromosome 7q22 within the autism susceptible locus (AUTS1); identified in(More)
Serotonin transporter (5-HTT) is a transmembrane protein belonging to Na+/Cl- dependent membrane transporter family and transports 5-HT across the membranes of presynaptic neurons. 5-HTT-linked polymorphic region (5-HTTLPR) gained much interest because of the differential regulation of expression and activity of 5-HTT by its various genotypes. A(More)
Involvement of reelin with Autism spectrum disorder (ASD) has been implicated through several biochemical as well as genetic studies. Reelin is an extracellular signaling protein, which plays a significant role in cytoarchitectonic pattern formation of different brain areas during development. Reelin gene (RELN) is located on chromosome 7q22; an important(More)
Mechanisms underlying Down syndrome (DS)-related mental retardation (MR) remain poorly understood. In trisomic offspring, non-disjunction may result in the reduction to homozygosity of a susceptibility allele inherited from a heterozygous parent. Accordingly, we sought evidence for allelic non-disjunction in the GluK1 gene that encodes the critical(More)
