Question
What does it mean when a heterozygous mutation is found in an infant’s hearing screening?
Answer
This situation may indicate that the child is simply a carrier and there is no need to be overly concerned. Heterozygous mutations usually come from the child’s parents’ genetics, although they may lead to a decrease in hearing, they typically do not require immediate medical intervention. It is sufficient to closely monitor the child’s hearing development and regularly conduct checks on auditory and language development.
