We report on two sibs, brother and sister, with a multiple congenital anomaly/mental retardation syndrome consisting of severe growth and mental retardation, seizures, retinal abnormalities, osteodysplasia, brachydactyly, prognathism, and dental malocclusion. These clinical findings were present in both patients and seem to be consistent with the phenotype of the Gurrieri syndrome. The new features described in these sibs could expand the clinical spectrum of the Gurrieri syndrome and confirm the existence of this rare autosomal recessive condition.

We report on a male with severe mental retardation, epilepsy, short stature, and skeletal dysplasia. The syndrome was first delineated by Gurrieri et al. in 1992 [Am J Med Genet 44:315-320]. This case seems to confirm the existence of the Gurrieri syndrome.

We report two unrelated patients, a three-year-old girl and an 88/12 year-old boy with the newly described "acrocallosal" syndrome. The main manifestations of the syndrome are unusual facial appearance, pre- and postaxial polydactyly, mental retardation, and absence of the corpus callosum. Cause remains unknown.

A patient with the velo-cardio-facial syndrome is described. The most frequent features include cleft palate, cardiac anomalies, typical facies, and learning disabilities. Less frequent findings include microcephaly, mental retardation, small stature, slender hands and digits, minor auricolar anomalies, and inguinal hernia. There were four instances of familial transmission in the 39 patients of the literature.
