Neural selectivity for communicative auditory signals in Phelan-McDermid syndrome.

Background: Phelan-McDermid syndrome (PMS), a neurodevelopmental disorder caused by deletion or mutation in the SHANK3 gene, is one of the more common single-locus causes of autism spectrum disorder (ASD). PMS is characterized by global developmental delay, hypotonia, delayed or absent speech, increased risk of seizures, and minor dysmorphic features. Impairments in language and communication are one of the most consistent characteristics of PMS.

Self-injury in autism spectrum disorder: an effect of serotonin transporter gene promoter variants.

Self-injurious behavior in autism spectrum disorder (ASD) has been associated with lower whole blood serotonin levels and the role of serotonin transporter gene promoter region (5HTTLPR) polymorphisms is of interest because of their effects on transporter functioning. This study examined the association between self-injurious behavior in ASD and allelic frequencies of 5HTTLPR. Sixty-four children and adolescents with ASD who were not taking serotonergic medication at the time of the assessment were included in the analysis.

Zn2+ mediates high affinity binding of heparin to the αC domain of fibrinogen.

The nonspecific binding of heparin to plasma proteins compromises its anticoagulant activity by reducing the amount of heparin available to bind antithrombin. In addition, interaction of heparin with fibrin promotes formation of a ternary heparin-thrombin-fibrin complex that protects fibrin-bound thrombin from inhibition by the heparin-antithrombin complex. Previous studies have shown that heparin binds the E domain of fibrinogen.

Prospective investigation of autism and genotype-phenotype correlations in 22q13 deletion syndrome and SHANK3 deficiency.

Background: 22q13 deletion syndrome, also known as Phelan-McDermid syndrome, is a neurodevelopmental disorder characterized by intellectual disability, hypotonia, delayed or absent speech, and autistic features. SHANK3 has been identified as the critical gene in the neurological and behavioral aspects of this syndrome. The phenotype of SHANK3 deficiency has been described primarily from case studies, with limited evaluation of behavioral and cognitive deficits.

The assessment of decisional capacity.

The physician must explain the treatment or procedure in detail including risks, benefits, and alternative options; the patient's choice must be voluntary; the patient must demonstrate his or her ability to understand the risks and benefits of their choice; and the patient must be able to manipulate information in a logical way. These criteria must be met in order for the process of informed consent to be valid.
