What is a characteristic of Usher's Syndrome Type 1?

Usher's Syndrome Type 1 is characterized by congenital deafness and progressive vision loss, which makes the choice indicative of its defining features. Individuals with this syndrome typically experience profound sensorineural hearing loss at birth, which is coupled with balance issues due to vestibular dysfunction. As they grow, they develop vision problems, specifically retinitis pigmentosa, which can lead to complete blindness over time.

This choice captures the essence of the syndrome's progression, whereby affected individuals are born with significant hearing loss and balancing difficulties, which is a hallmark of Type 1, before experiencing the onset of vision loss later on. The other options do not accurately reflect this syndrome's characteristics, as they either suggest normal hearing at birth or delay the onset of symptoms that are actually present from early life in Type 1.
