Locating genes for cognitive traits using linkage and association analyses

点击翻译按钮获取中文摘要

Our study is the 1st in the world to find significant linkage for IQ.The dataset is one of only 2 such in the world (based on sample size, range & type of measures).Identifying genes for cognitive ability using healthy subjects is important in understanding individual differences in normal cognitive functioning, but it may also provide clues into the underlying mechanisms of impaired cognitive ability. Diverging conditions like reading disorder, schizophrenia, depression, alcoholism, and dementia all share deficits in cognitive ability.Downstream practical applications of identifying 'genes for cognition' include better educational, behavioural and biomedical management of learning and memory disorders, and other intellectual disabilities.
