The authors describe two sisters with the typical characteristics of cranio-metaphyseal dysplasia and mental retardation. They also discuss a cause-and-effect nature of the pathogenetic relationship of the intellectual deficiency and the systemic bone hereditary damage as well as the difficulty of assessing the type of heredity in the given family.

To reveal constitutional liability of children with mental retardation (MR), dactiloscopy was performed in 200 children with MR of a cerebral-organic genesis (129 boys and 61 girls), 110 normal children (56 boys and 54 girls) and 95 children with an undifferentiated form of oligophrenia at the stage of debility (68 boys and 27 girls). It was found that mentally retarded children as compared to normal children more frequently had a pattern of the "coil" type, dysplasia of the crest lines, less marked bimanual symmetry of patterns and less pronounced sex differences in the frequency of finger patterns.

We describe a familial syndrome of renal dysplasia, Wilms tumor, hyperplasia of the endocrine pancreas, fetal gigantism, multiple congenital anomalies and mental retardation. This condition was previously described by Perlman et al [1973, 1975] and we propose to call it the "Perlman syndrome." It appears to be transmitted as an autosomal recessive trait. The possible relationships between dysplasia, neoplasia and malformation are discussed.

A patient had a parathyroid adenoma and prolactin-secreting pituitary tumor, suggestive of the multiple endocrine neoplasia (MEN) I syndrome. The presence of a marfanoid habitus--found more typically in MEN III syndrome--as well as mitral valve prolapse, mental retardation, and bilateral optic atrophy suggests a new variant of the MEN syndrome, possibly representing widespread dysplasia of endocrine and other tissues.

An 18-year-old boy showed childhood onset of mental retardation, neurogenic muscle atrophy with hyperreflexia, Marfan-like features, multiple epiphyseal dysplasia, increased urinary excretion of dermatan sulfate, and decreased lysosomal enzyme activities in beta-galactosidase, beta-glucuronidase, and N-acetyl-beta-D-glucosaminidase. This case may be a new syndrome, the combination of neurogenic muscle atrophy with lysosomal enzyme deficiencies.

Within the heterogeneous group of microcephalies, a syndrome can be defined characterized by microcephaly, mental retardation, and chorioretinal dysplasia, often also with microphtalmia and embryonic remnants such as persistance of the primitive vitreum. Although this condition is usually considered autosomal recessive, the authors report a family observation consistent with dominant transmission.

Human chromosome disease arises from a change in the number or structure of one or more chromosomes. The multiple genes represented in the duplicated or deleted chromosomes are not usually defective and any systemic abnormalities can be attributed to a change in gene dosage. Banding techniques are now commonly used to identify each chromosome and the specific chromosome duplication and deletion and structural rearrangements can now be identified unambiguously. Most ocular abnormalities have occurred in patients with chromosomal defects. Major ocular abnormalities, such as anophthalmia, cyclopia, retinoblastoma, microphthalmia, corneal opacities, coloboma, cataracts, intraocular cartilage, retinal dysplasia and absent optic nerves; and, minor abnormalities, such as ptosis, abnormal eyelid fissures, and Brushfield spots are present in individuals with abnormal chromosomes. The chromosome errors are usually present in all somatic tissues. consequently, multiple tissue abnormalities would be expected in most patients with chromosome abnormalities. Mental retardation is very common in those patients with abnormalities of autosomes. Therefore, it is unlikely that an isolated single clinical or histopathological ocular abnormality will be the result of a chromosome error. However, if the individual has multiple systemic abnormalities, then a chromosome error can be considered reasonably. Any chromosome disorder can be identified correctly by an appropriate banding chromosome determination on the affected individuals. With the possible exception of the association of 13q 14- and retinoblastoma, there does not appear to be any pathognomonic ocular abnormalities that occur in individuals with chromosome errors.

We report a 5-year-old boy affected with the Tay syndrome, and give a review of 12 pertinent cases previously reported under various designations. The Tay syndrome is a distinct type of congenital ichthyosis characterized by a peculiar anomaly of hair growth which has been termed trichothiodystrophy. The hair shafts are extremely brittle, and they show alternating light and dark banding when examined microscopically between polarizing filters. Other features of this syndrome are low birth weight, short stature, mental retardation, delayed neuromuscular development and other CNS anomalies, dysplasia of nails, hypoplasia of subcutaneous fatty tissue, prematurely aged facial appearance, hypogonadism, cataracts, osteosclerosis, dysphonia, and increased susceptibility to infections. The syndrome is inherited as an autosomal recessive trait. We delineate the criteria for distinguishing this gene defect from other types of congenital ichthyosis associated with disturbed hair growth, as well as from other types of trichothiodystrophy which are not associated with ichthyosis.

Golabi and Rosen (1984) have reported on a new X-linked mental retardation/multiple congenital anomalies (XLMR/MCA) syndrome of pre- and postnatal overgrowth, characteristic "coarse" facial appearance with macrostomia, midline groove of tongue, lower alveolar ridge and lip, submucous cleft of palate, supernumerary nipples, intestinal anomalies, supernumerary pair of ribs, anomalies of sacrum and tailbone, hypoplastic index fingernails, postaxial polydactyly and other digital anomalies. This was an incompletely recessive trait with some manifestations evident in an obligatory carrier. Here we report on a second family (studied at the University of Wisconsin for over 9 years) in which 3 males born to half-sisters and their mother were affected with the Golabi-Rosen syndrome (GRS). Overgrowth was not a prominent manifestation in these affected males. Presence of cystic kidneys, peculiar skin changes and hepatomegaly make it likely that the Golabi-Rosen syndrome is an X-linked MCA/dysplasia/MR syndrome. Its metabolic basis remains unknown. It seems to be an incompletely recessive trait.

The fact that a connective tissue dysplasia is a component of the Martin-Bell syndrome was a fortuitous discovery. A 26-month-old developmentally delayed boy had many signs of a connective tissue dysplasia for which he was referred to a University center where he was found to be fragile (X)-positive without confirmation of a connective tissue problem. Sensitized by these events and observations, we were able to predict at a glance in an unrelated family the fragile (X)-positive status of 2 subsequently referred brothers with mental retardation and prominent manifestations of connective tissue dysplasia. Thus, the Martin-Bell syndrome is an incompletely recessive, pleiotropic trait involving CNS, testes and connective tissues. The characteristic facial appearance of affected males largely represents interaction of mental retardation, congenital CNS based muscle hypotonia and connective tissue dysplasia. At the 1983 NIH workshop on XLMR there was a general consensus that a connective tissue dysplasia is a component of the Martin-Bell syndrome, a fact since confirmed by others on the basis of objective measurements of finger joint hypermobility and frequent presence of mitral valve prolapse.
