Misspecification in mixed-model based association analysis

, 2015
Additive genetic variance in natural populations is commonly estimated using mixed models, in which the covariance of the genetic effects is modeled by a genetic similarity matrix derived from a dense set of markers.

Psychiatric genetics and the structure of psychopathology [PDF]

, 2018
For over a century, psychiatric disorders have been defined by expert opinion and clinical observation. The modern DSM has relied on a consensus of experts to define categorical syndromes based on clusters of symptoms and signs, and, to some extent ...

Molecular Profiling of Genes Associated With Methylphenidate Pathway Therapy and Discovery of New Variants in Amazonian Amerindian Populations

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In Attention Deficit Hyperactivity Disorder (ADHD), methylphenidate is one of the most widely used drugs, in which patient response significantly impacts prognosis. This study aimed to characterize the molecular profile of 10 genes associated with methylphenidate therapy.

Accurate and efficient estimation of local heritability using summary statistics and the linkage disequilibrium matrix

Nature Communications, 2023
Existing SNP-heritability estimators that leverage summary statistics from genome-wide association studies (GWAS) are much less efficient (i.e., have larger standard errors) than the restricted maximum likelihood (REML) estimators which require access to

Patient Perspectives on Psychiatric Polygenic Risk Scores in Reproductive Decision‐Making and Polygenic Embryo Screening

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Polygenic risk scores (PRS) estimate individuals' genetic risk for developing multifactorial conditions. Recent genome‐wide association studies have enabled development of psychiatric PRS, which hold potential to streamline diagnosis and treatment of psychiatric conditions.

Genome‐Wide Association Study of Symptom Change Following Cognitive Behavioral Therapy for Common Mental Disorders

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Cognitive behavioral therapy (CBT) is a well‐established, evidence‐based treatment for common mental disorders such as depression, anxiety disorders, and obsessive‐compulsive disorder (OCD). However, treatment outcomes vary widely, and a substantial proportion of patients do not achieve sufficient improvement.

Interrogating the Genetic Determinants of Tourette’s Syndrome and Other Tic Disorders Through Genome-Wide Association Studies [PDF]

, 2019
Objective: Tourette’s syndrome is polygenic and highly heritable. Genome-wide association study (GWAS) approaches are useful for interrogating the genetic architecture and determinants of Tourette’s syndrome and other tic disorders. The authors conducted

“It's Not Deterministic and It Will Never Be Deterministic”: A Qualitative Study on Stakeholder Perspectives of Polygenic Risk Score Testing for Post‐Traumatic Stress Disorder

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Post‐traumatic stress disorder (PTSD) causes significant mental and physical distress, yet only a small subset of individuals exposed to trauma develop the disorder. Scientists and clinicians are still unable to predict who will get the disorder or how it will manifest.

SNP-based heritability estimation using a Bayesian approach

Animal, 2013
Heritability is a central element in quantitative genetics. New molecular markers to assess genetic variance and heritability are continually under development. The availability of molecular single nucleotide polymorphism (SNP) markers can be applied for
