A new study from University of Bristol shows the development of genes in children can contribute to language development.

Researchers said they there's a link between the genetic changes of the ROBO2 gene and the number of words a child can speak during his language development.

ROBO2 is a gene that creates the ROBO2 protein that directs chemicals in the brain and other neurons for cell formation. It can help in the language development of a child.

According to researchers, children can produce words as early as 10 to 15 months.  When they reach 15 to 18 months, they can already produce 50 words.

Around 18 to 30 months they can already produce 200 words. By the time they reach six years old, they can already produce 14,000 words.

When they leave secondary school, children can already produce 50,000 words, researchers said.

Beate St. Pourcain, one of the researchers, said this research helps them understand the factors that involve language development of children.

St. Pourcain said there's a link between the ROBO proteins and the linguistic development of children.

Claire Haworth, another researcher involved in the study, said genetic development is connected with language development. She believes this is good news for DNA-based investigations related to speech development.

Haworth said their findings could be used to detect the genetic factors that contribute to the language development of children.

Researchers believe their findings could help in the development of treatments for dyslexia and other speech related disorders.
