Rs1805054
Encyclopedia
In genetics
, Rs1805054, also called C267T, is a name used for a specific genetic variation, a single nucleotide polymorphism
(SNP), in the HTR6 gene
.
It is one of the few investigated polymorphisms of its gene.
C267T is a synonymous polymorphism.
As of 2008 meta-analysis
of the polymorphism and Alzheimer's disease
indicates that there probably is no association between the two,
though individual studies report such an association, e.g., a Chinese study found an association with late-onset Alzheimer's disease.
Another reported association in neuropsychiatry disorders is with treatment response in depression.
C267T has also been examined in relation to personality traits, with a Korean study finding some evidence for an association with the trait self-transcendence.
A Japanese study reported no association with personality traits using the NEO PI-R personality inventory.

Single nucleotide polymorphism
A single-nucleotide polymorphism is a DNA sequence variation occurring when a single nucleotide — A, T, C or G — in the genome differs between members of a biological species or paired chromosomes in an individual...

Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

Meta-analysis
In statistics, a meta-analysis combines the results of several studies that address a set of related research hypotheses. In its simplest form, this is normally by identification of a common measure of effect size, for which a weighted average might be the output of a meta-analyses. Here the...

Alzheimer's disease also known in medical literature as Alzheimer disease is the most common form of dementia. There is no cure for the disease, which worsens as it progresses, and eventually leads to death...
