Microdeletion and microduplication syndromes.
The widespread use of whole genome analysis based on array comparative genomic hybridization in diagnostics and research has led to a continuously growing number of microdeletion and microduplication syndromes (MMSs) connected to certain phenotypes. These MMSs also include increasing instances in which the critical region can be reciprocally deleted or duplicated. This review catalogues the cur...
متن کاملPsoriasis and psychiatry: an update.
Psychosocial factors are important in the onset and/or exacerbation of psoriasis in 40%-80% of cases. Yet psoriasis has received little attention in the recent psychiatric literature. A subgroup of psoriatics appear to be "stress reactors" and these patients may have a better long-term prognosis. Identification of such patients early in the course of treatment and incorporation of specific psyc...
متن کاملInsights into Common Microdeletion Syndromes
Microdeletion syndromes are due to submicroscopic chromosomal deletions and display a complex clinical and behavioral phenotype. This occurs because of an imbalance of normal dosage of genes that are present in that segment of chromosome. Many clinical characteristics of the well-known microdeletion syndromes are very specific and have been well defined. It is not always possible to detect thes...
متن کاملMicrodeletion syndromes, balanced translocations, and gene mapping.
High resolution prometaphase chromosome banding has allowed the detection of discrete chromosome aberrations which escaped earlier metaphase examinations. Consistent tiny deletions have been detected in some well established malformation syndromes: an interstitial deletion in 15q11/12 in the majority of patients with the Prader-Willi syndrome and in a minority of patients with the Angelman (hap...
متن کاملPeriventricular heterotopia in common microdeletion syndromes.
Periventricular heterotopia (PH) is a brain malformation characterised by heterotopic nodules of neurons lining the walls of the cerebral ventricles. Mutations in FLNA account for 20-24% of instances but a majority have no identifiable genetic aetiology. Often the co-occurrence of PH with a chromosomal anomaly is used to infer a new locus for a Mendelian form of PH. This study reports four PH p...
