Summary of "Expanding the toolbox of ADHD genetics. How can we make sense of parent of origin effects in ADHD and related behavioral phenotypes?"

Genome-wide association (GWA) studies have shown that many different genetic variants cumulatively contribute to the risk of psychiatric disorders. It has also been demonstrated that various parent-of-origin effects (POE) may differentially influence the risk of these disorders. Together, these observations have provided important new possibilities to uncover the genetic underpinnings of such complex phenotypes. As POE so far have received little attention in neuropsychiatric disorders, there is still much progress to be made. Here, we mainly focus on the new and emerging role of POE in attention-deficit hyperactivity disorder (ADHD). We review the current evidence that POE play an imperative role in vulnerability to ADHD and related disorders. We also discuss how POE can be assessed using statistical genetics tools, expanding the resources of modern psychiatric genetics. We propose that better comprehension and inspection of POE may offer new insight into the molecular basis of ADHD and related phenotypes, as well as the potential for preventive and therapeutic interventions.

We determined the validity of a parent-report questionnaire as a research tool for rating attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Using Cohen's kappa and Pearson correlat...

An exploratory study of parent-child association in sensory modulation disorder involving ADHD-related symptoms.

Sensory modulation disorder (SMD) and attention deficit hyperactivity disorder (ADHD) can co-occur and have overlapping symptoms, thus challenging practitioners. This study aimed to phenotypically exp...

Two Powerful Tests for Parent-of-Origin Effects at Quantitative Trait Loci on the X Chromosome.

Parent-of-origin effects, which describe an occurrence where the expression of a gene depends on its parental origin, are an important phenomenon in epigenetics. Statistical methods for detecting pare...

High pretreatment cognitive impulsivity predicts response of oppositional symptoms to methylphenidate in patients with attention-deficit hyperactivity disorder/oppositional defiant disorder.

Medical and Biotech [MESH] Definitions

A natural, adoptive, or substitute parent of a dependent child, who lives with only one parent. The single parent may live with or visit the child. The concept includes the never-married, as well as the divorced and widowed.

Performing the role of a parent by care-giving, nurturance, and protection of the child by a natural or substitute parent. The parent supports the child by exercising authority and through consistent, empathic, appropriate behavior in response to the child's needs. PARENTING differs from CHILD REARING in that in child rearing the emphasis is on the act of training or bringing up the children and the interaction between the parent and child, while parenting emphasizes the responsibility and qualities of exemplary behavior of the parent.

The presence in a cell of two paired chromosomes from the same parent, with no chromosome of that pair from the other parent. This chromosome composition stems from non-disjunction (NONDISJUNCTION, GENETIC) events during MEIOSIS. The disomy may be composed of both homologous chromosomes from one parent (heterodisomy) or a duplicate of one chromosome (isodisomy).

Attachment of the child to the parent of the opposite sex, accompanied by envious and aggressive feelings toward the parent of the same sex.

The authorized absence from work of a family member to attend the illness or participate in the care of a parent, a sibling, or other family member. For the care of a parent for a child or for pre- or postnatal leave of a parent, PARENTAL LEAVE is available.
