Having a close relative with reading difficulties, or having a family history of dyslexia, is one of the highest risk factors for the condition. The heritability of dyslexia is approximately 50%, according to research comparing identical and nonidentical twins.A child who has a dyslexic parent is at an increased chance of the condition by 40–60%. When other family members are impacted, this risk is increased.
Your genes contribute to roughly half of your reading skills, while your upbringing and environment account for the other half. However, dyslexia is a complicated cognitive problem that is distinct from the proteins whose synthesis genes regulate, making it challenging to understand how genetic and environmental variables interact to cause reading difficulties.
It is believed that dyslexia is a neurobiological condition with genetic roots. The functioning of the nervous system is impacted by this condition, which people can inherit from their parents (specifically, the parts of the brain responsible for learning to read).
It’s not unusual for a youngster with dyslexia to share the condition with a member of their close family. Additionally, it’s not uncommon for a family to have two or more kids with this kind of learning difficulty.
If an older relative left school before the condition was identified, it could be difficult to tell if they have dyslexia. Your ancestors may have been dyslexic if they “hated school,” were “drop-outs,” or left school early to enlist in the military or find employment. Without the right support,school might have turned out to be a very unpleasant and unfulfilling experience for them.
Unfortunately, very young poor readers frequently develop into poor readers as adults unless they receive the appropriate services early in life. The good news is that the earlier dyslexic children receive the appropriate teaching, especially in the very early grades, the more likely it is that they will experience fewer or milder issues in adulthood.
Young children with dyslexia need to be exposed to a systematic, persistent early education program designed to help them form the linkages between letters and the sounds they make in order to be successful readers. Dyslexia training program can assist parents and teachers to learn more about dyslexia.
Is dyslexia genetic or can dyslexia be inherited?
Probably a significant part of dyslexia’s causes is genetic. Because dyslexia frequently runs in families, we are aware of this.
But it’s not entirely genetic. Since identical twins share the same DNA, if dyslexia were entirely hereditary, the two people would always agree. Usually, but not usually, they both suffer from the disease.
No single “dyslexia gene” exists. Over 40 genes have already been connected in some way to dyslexia. Each gene probably only has a modest individual impact. There isn’t actually a single “dominant” or “recessive” gene in a genetically complex disorder like this one.
The genes linked to dyslexia have a wide range of functions. Many of these genes influence the connections between brain cells. Other genes have an impact on the structure and intercellular communication of cells.
Even while we’ve come a long way, much more investigation will be necessary before we fully comprehend how genetic variations could lead to dyslexia.
Does it matter more if the father has dyslexia than the mother?
No. Boys are diagnosed with dyslexia significantly more frequently than girls are, and a few genes linked to the disorder are located on the X chromosome. There isn’t any proof, though, that having dyslexia increases your chances of inheriting it from one parent over the other.
We are aware that there are other risk factors in addition to genes that contribute to dyslexia, as you noted.You can sign up for dyslexia training program to know more about dyslexia.
