How do genes influence the development of speech of the child?

About ROBO2 gene corresponding to the development of speech, dyslexia causes and influence of heredity on the ability to speak.

September 16, 2014, British scientists published in the journal Nature Communications article on a gene that influences the development of speech in children. They had found a gene that affects how many words will be able to pronounce the child at an early age.

Handling of British scientists is very interesting and contributes to the understanding of what and how to identify the genes in the development of the child, in the formation of the features of an adult.
Children begin to talk at different ages, and when one is already in full talks, another still just says a few words. As it turned out, the number of words that says a child under the age of 3 years, depends not only on how parents communicate with him, but also on the genes. Actually, the fact that the genes for the ability to affect speech learning, it was known before. But now we found a specific gene with which it is associated impact. The gene is called ROBO2. Children with one embodiment vocabulary gene are more than the other. Interestingly, the gene is located on the 3rd chromosome, near the site, which is known that it is associated with dyslexia - a violation of learning to read, while maintaining intellectual abilities. Some of the children are not able to learn to read not from the fact that they are poorly taught, and because the genes they "do not give." For example, due to the genetic characteristics of the child can not coordinate eye movements that they followed along the lines of letters, or has violated phonemic hearing. For such children need special training program to teach them to read.

For improvement speaking ability of children doctors often recommend to buy Semax, Cogitum, Picamilon, Cortexin, Selank.

But in the study in question, we studied healthy children. And this is important - to understand how genes provide the normal development and because of what it can be broken. In order to understand this, geneticists are regions of the genome, variations in which are linked to the characteristics of the person, and then begin to understand what is written in these areas, what are the functions of the genes that are found. This story was with another gene important to the ability to speak. It FOXP2 gene. Mutations of this gene found in a family whose members were unable to master the grammar. This caused great interest, because the ability to speak - a key feature that distinguishes man from other animals. Gene carefully studied and found that it works during embryonic development in those areas of the brain that are associated with speech. Moreover, it turned out that FOXP2 evolved a special way a person does not like his closest relatives, monkeys, or other animals. Although they have this gene busy "verbal" functions. For example, song birds it affects the learning song.
There is no doubt that ROBO2 gene comprehensively examine these studies will be useful for the development of medicine or pedagogy. The ability to speak - a very important property of the person. It is necessary all the time to write about what beneficial results of this study bring. But, in addition to utility, it is also quite fascinating - to understand how genes "do" person, and what role they play in how we differ from each other. For example, Richard Feynman talking about physics: "Physics is like sex: specifically, it may give some practical results, but we are doing it not because of this." The study of the genome is no worse than physics, and maybe even more fun.
