What are the symptoms of MSS?
Some symptoms occur in almost all reported cases of MSS. These symptoms include cataracts (progressive loss of transparency of the eye lens), ataxia (impaired ability to coordinate movement), hypotonia (floppiness), short stature, dysarthria (slow, weak, or imprecise speech due to weakness or incoordination of speech muscles), and mental retardation (generally in the mild-moderate range). Other symptoms such as hypergonadotropic hypogonadism (decreased function of the ovary/testis), nystagmus (involuntary, rhythmic movements of the eyes) and skeletal abnormalities are reported less frequently.
