English to Russian Medical Genetics

Context:
Some children with GRIN2A related syndrome have inherited the mistake in the GRIN2A gene from one of their parents. The mistake may be present in their grandparents and earlier generations. The features of GRIN2A related syndrome can vary between family members. For instance, different forms of epilepsy as a result of GRIN2A related syndrome can occur within one family. Some family members who carry the mistake in the GRIN2A gene may not appear to have any symptoms or features, while other family members are affected. In some children the sequence change in GRIN2A occurred out of the blue (de novo). The parents were not found to carry the change in GRIN2A.
