... Craig & Plomin, 2002). The authors reported on the genotyping of the FOXP2 mutation for 270 four-year olds selected for low language scores from a representative sample of more than 18,000 children. Not a single one of the language-impaired children turned out to have the FOXP2 mutation (Meaburn, et ...

... A phenogram of a CNV represents the network of genes and related phenotypes that have been associated with the genes in a particular CNV interval. All phenotype matches above a threshold, calculated based on the phenotype IC of the closest match (Resnik, 1995), are used to form a phenogram. For exam ...

Epigenetics of human development

Development before birth, including gametogenesis, embryogenesis, and fetal development, is the process of body development from the gametes are formed to eventually combine into a zygote to when the fully developed organism exits the uterus. Epigenetic processes are vital to fetal development due to the need to differentiate from a single cell to a variety of cell types that are arranged in such a way to produce cohesive tissues, organs, and systems.Epigenetic modifications such as methylation of CpGs (a dinucleotide composed of a 2'-deoxycytosine and a 2' deoxyguanosine) and histone tail modifications allow activation or repression of certain genes within a cell, in order to create cell memory either in favor of using a gene or not using a gene. These modifications can either originate from the parental DNA, or can be added to the gene by various proteins and can contribute to differentiation. Processes that alter the epigenetic profile of a gene include production of activating or repressing protein complexes, usage of non-coding RNAs to guide proteins capable of modification, and the proliferation of a signal by having protein complexes attract either another protein complex or more DNA in order to modify other locations in the gene.
