Localised duplications, involving the MECP2 locus, at Xq28 have been associated with a syndrome comprising X-linked mental retardation, hypotonia and recurrent infections in males. We now present neuroradiological evidence that progressive cerebellar degenerative changes may also be a consistent feature of this syndrome, emerging in the second decade of life. ...

Sjögren-Larsson syndrome is an autosomal-recessive hereditary disorder involving congenital ichthyosis, mental retardation, and spastic diplegia or tetraplegia. It is caused by the deficient activity of fatty aldehyde dehydrogenase. In this report, the authors describe 2 siblings with Sjögren-Larsson syndrome. Both the patients had generalized ichthyosis, and the older one had ...

We describe two children from a consanguineous family who manifested mega-corpus callosum, polymicrogyria, and psychomotor retardation. These patients also exhibited the brain anomalies of pontine hypoplasia and an abnormal cerebellar vermis. Our report confirms the genetic nature of megalencephaly-polymicrogyria-mega-corpus callosum syndrome, suggests a possible autosomal-recessive inheritance, and expands the spectrum ...

The hypothalamo-pituitary-adrenal axis has not been studied systematically in Noonan syndrome (NS), despite potential concerns about other aspects of hypothalamo-pituitary function. While adrenarche may be delayed in children with constitutional growth of puberty and in isolated GH deficiency, this does not generally seem to be the case in hypergonadotrophic hypogonadism ...

Structural chromosomal rearrangements can lead to a wide variety of serious clinical manifestations, including mental retardation (MR) and congenital malformations. Over the last few years, rearrangements below the detection level of conventional karyotyping have been proved to contribute significantly to the cause of MR. These so-called copy number variations are ...

Down syndrome (trisomy 21) is the most common cause of mental retardation in children and leads to marked deficits in contextual learning and memory. In rodents, these tasks require the hippocampus and are mediated by several inputs, particularly those originating in the locus coeruleus. These afferents mainly use norepinephrine as ...

It is well known that a deletion within chromosome 22q11.2 has been identified in most cases of congenital heart disease (CHD) with DiGeorge syndrome (DGS) and velo-cardio-facial syndrome (VCFS). Whether the 22q11.2 deletion is associated with isolated CHD is controversial. Our data is consistent with previous publications which show that ...

Overgrowth syndromes are a heterogeneous group of conditions including endocrine hormone disorders, several genetic syndromes and other disorders with unknown etiopathogenesis. Among genetic causes, chromosomal deletions and duplications such as dup(4)(p16.3), dup(15)(q26qter), del(9)(q22.32q22.33), del(22)(q13) and del(5)(q35) have been identified in patients with overgrowth. Most of them, however, remain undetectable using ...

Pathogenic variations of the ARX (aristaless-related homeobox) gene are associated with marked phenotypic pleiotropy. These phenotypes are X-linked neurological disorders that include brain and genital malformation and non-malformation syndromes. Typically, malformation phenotypes result from pathogenic variations that are predicted to truncate the ARX protein, or alter residues in the highly ...

Array comparative genomic hybridization studies were performed to further characterize cytogenetic abnormalities found originally by karyotype and fluorescence in situ hybridization in five clinical cases of distal 10q deletions, including several with complex cytogenetic rearrangements and one with a partial male-to-female sex-reversal phenotype. These results have enabled us to narrow ...

BACKGROUND: The use of array comparative genome hybridisation (CGH) analyses for investigation of children with mental retardation has led to the identification of a growing number of new microdeletion and microduplication syndromes, some of which have become clinically well characterised and some that await further delineation. This report describes three ...
