The genetic diseases were heterogeneous and included a case of mosaicism with Robert's syndrome, phocomelia, mild mental retardation, optic atrophy, bilateral facial palsy (Hasegawa et al, 1998), a case with Prader-Willi syndrome (Gau et al, 1996), an unidentified disease with mental retardation and bilateral pyramidal syndrome (Livrea et al, 1977), another complex case of consanguinity, mental retardation, an ectodermal disorder (incontinentia pigmenti), acanthosis nigricans, and hereditary exostosis (Reimao and Shimizu, 1998) and developmental Asperger's disease in two patients, one with cortical dysplasia and retinitis pigmentosa (Berthier et al, 1992). As for the three patients with infectious encephalitis of unknown origin, one had an acute viral meningo-encephalitis and high CSF lymphocyte counts (Merriam, 1986) while another had a meningo-encephalitis with neurological sequels, including left hypo-sensitivity, central facial palsy, concentric loss of visual fields and bilateral facial spasms (Persson et al, 1969).…”
