Born at term after normal pregnancy; Birth w, l and OFC on the 3rd centile. At 1y statomotoric retardation; muscular hypotonia; microcephaly; dysmorphic features (mild high-arched palate, epicanthal folds); sitting at 1y. Up 2y no walking or standing upright without support; lack of language development, audiological tests normal. At 3.5y language and motor development delay; able to walk but used no language. Head circumference, height and weight between the 3rd and 10th centile. Motor skills and social interaction were decreased without autistic symptoms plus an attention deficit disorder. At seven years, progressed due to a special kindergarten program and showed age-matched social interaction.
