As a result, one or more of the parent’s children may inherit the gene mutation, potentially leading to manifestation of the disorder, while the parent may have no apparent symptoms (asymptomatic carrier). [rarediseases.org]

Affected infants may fail to grow and gain weight at the rate expected for age and gender (failure to thrive). Growth deficiencies may ultimately result in a final adult height that is below normal (short stature). [rarediseases.org]

Although the eruption usually resolves during infancy, older children may subsequently develop inflammation and wasting (atrophy) of follicles (follicular atrophoderma), causing pores to appear unusually large. [rarediseases.org]

Cataracts can caused blurred vision or decreased clarity of vision. [rarediseases.org]
