Both presented the distinct association of (1) a non-progressive neurological syndrome with ataxia and hypotonia, (2) similar craniofacial appearance with a narrow forehead, prominent supraorbital ridges and tendency to synophrys, deeply set eyes with short, upward slanting palpebral fissures, short philtrum, and large mouth, (3) hypergonadotrophic hypogonadism, and (4) retinal dystrophy with onset in early adulthood.
