Feedback:
NF-2, which is characterized by tumors of the acoustic nerve and multiple meningiomas, is much less common than NF-1. The disorder is often asymptomatic through the first 15 years of life. The most frequent symptoms are headaches, hearing loss, and tinnitus. Infants with Tay-Sachs disease appear normal at birth but begin to manifest progressive weakness, muscle flaccidity, and decreased attentiveness at approximately 6 to 10 months of age. Fragile X syndrome, an abnormality in the X chromosome, is the common cause of inherited intellectual disability.
