Mendelian randomization: Principles and methods [PDF]

Mendelian randomization (MR) is a methodology for evaluating causality in observational studies. MR tries to find the fact that genotypes are not susceptible to reverse causation and confounding based on Mendel's law of inheritance.

Severe Phenotype in an Indian Family With Progressive Pseudorheumatoid Arthropathy of Childhood

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a rare autosomal recessive progressive condition that affects the cartilage of joints and bones. The symptoms of PPAC include stiffness of the joints, bony swelling of the toes and fingers, short stature, kyphosis, and muscle weakness.

Genotype–Phenotype Correlations of Monoallelic PFIC Variants in Pediatric Liver Disease: A Multicenter Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive familial intrahepatic cholestasis (PFIC) is classically caused by biallelic pathogenic variants, yet monoallelic variants of uncertain significance (VUS) in PFIC‐associated genes are increasingly identified in children with cholestasis, creating diagnostic uncertainty.

An alternative to Kitcher's theory of conceptual progress and his account of the change of the gene concept [PDF]

, 2004
The present paper discusses Kitcher’s framework for studying conceptual change and progress. Kitcher’s core notion of reference potential is hard to apply to concrete cases.

Exome Sequencing Uncovers Phenotypic and Genotypic Heterogeneity in 196 Indian Families Evaluated for Autoinflammatory Disorders

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autoinflammatory disorders (AIDs) are a clinically heterogeneous group of inborn errors of immunity primarily caused by dysregulation in the innate immune system. Clinical diagnosis is often challenging due to clinical heterogeneity and the overlapping phenotypes with other inborn errors of immunity and monogenic conditions that mimic AIDs ...

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

Trace Elements Genetics: A Potential Role in Treatment‐Resistant Major Psychoses and Related Traits?

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Trace elements are pivotal to key biological processes, with possible effects on psychopathology. We investigated the hypothesis of shared genetic factors between trace elements levels, treatment resistance and related traits. We used genome‐wide summary statistics for trace elements blood concentration, treatment‐resistant depression (TRD ...
