Gareis-Mason syndrome
An inherited (genetic) syndrome with characteristic features including (1) neurologically: mental retardation and aphasia (lack of speech); (2) limbs: adducted (clasped) thumbs, absent extensor pollicis longus and/or brevis muscles to the thumb, shuffling gait, and leg spasticity; (3) growth: small body size; (4) skeleton: lumbar lordosis (sway back). The syndrome is inherited as an X-linked trait and so affects mainly boys.
