There is evidence for an association between structural variants in genes for lissencephaly, which are involved in neuronal migration, and prefrontal cognitive deficits in schizophrenia and bipolar patients. On the basis of these intriguing findings, we analyzed 16 markers located in the lissencephaly critical region (LCR in chromosome 17p13.3) in 124 schizophrenic, 56 bipolar, and 141 healthy individuals. All recruits were from a Spanish population isolate of Basque origin that is characterized by low genetic heterogeneity. In addition, we examined whether structural genomic variations in the LCR were associated with executive cognition. Twenty-three patients (12.8%), but none of the controls, showed structural variants (deletions and insertions) in either of two markers related with lissencephaly (D17S1566 on tumor suppressor gene TP53: tumor protein p53 and D17S22 on SMG6 gene: Smg-6 homolog, nonsense mediated mRNA decay factor- Caenorhabditis elegans). These patients performed significantly worse in the Wisconsin Card Sorting Test-Categories in comparison with patients without such variations in lissencephaly-related genes. The presence of structural variants was related to completed categories, and accounted for 10.7% of the variance (P=0.001). Finally, logistic regression showed that poor Wisconsin Card Sorting Test-Categories performance was the only predictor of belonging to the positive LCR variations group. These new findings provide further evidence for the association between some lissencephaly-related genes and both schizophrenia and bipolar disorder, and influence on frontal executive functioning.
These results suggest a role of CAPN5 gene in PCOS susceptibility in humans. Moreover, novel candidate risk alleles have been identified, within CAPN5 gene, which could be associated with important phenotypic and prognosis differences observed in PCOS patients.

AbstractThis article describes the different approaches that can be applied to the study of the concept of family resilience in the context of pediatric disease and their implications for clinical practice and education. It also describes the general principles that should govern this practice and the specific activities of the professional of health systems, educational and social. The resilience is essential to maintain a good quality of life of the sick and the family as a whole.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
