The acrocallosal syndrome in sisters.
Two sisters born to non-consanguineous healthy parents are described who present the following abnormalities: macrocephalus, prominent forehead, hypertelorism, absence of the corpus callosum, inguinal hernias, duplication of hallucal phalanges and severe mental retardation. The older sister in addition had cleft palate, while only the younger had a supratentorial cyst between cerebrum and cerebellum and epileptic fits. After 6 sporadic cases, this is the first instance of siblings with the acrocallosal syndrome. This observation and definite and possible parental consanguinity in two further patients suggest that this syndrome might be recessively inherited.
