The process of identifying and responding to patients' social, emotional, and psychological concerns is a required skill for training and practicing genetic counselors. Patients' health outcomes are improved when genetic counselors attend to these "psychosocial" concerns. Still, the process of eliciting, assessing, and attending to patients' psychosocial concerns in the genetic counseling setting is not well defined in the literature nor is it performed consistently.

Clinical features and outcomes in carriers of pathogenic desmoplakin variants.

Eur Heart J

September 2024

Division of Cardiology, Department of Medicine, Johns Hopkins University, 601 North Caroline St., Baltimore, MD 21287, USA.

Article Synopsis
  • Pathogenic variants in the desmoplakin (DSP) gene lead to a unique type of cardiomyopathy that doesn't fit neatly into existing categories like DCM, NDLVC, or ARVC, with limited past studies on potential predictors of severe outcomes.
  • Researchers analyzed 800 patients with DSP variants from a global network over an average of 3.7 years, finding that 17.4% experienced sustained ventricular arrhythmias (VAs) and 9.0% had heart failure (HF) hospitalizations.
  • Key risk factors for developing VAs included female sex, history of non-sustained and sustained VAs, and lower left ventricular ejection fraction, while T-wave inversion was linked to HF

Background: Hypertrophic cardiomyopathy (HCM) is an inherited cardiac condition affecting ~1 in 500 and exhibits marked genetic heterogeneity. Previously published in 2019, 57 HCM-associated genes were curated providing the first systematic evaluation of gene-disease validity. Here we report work by the ClinGen Hereditary Cardiovascular Disorders Gene Curation Expert Panel (HCVD-GCEP) to reappraise the clinical validity of previously curated and new putative HCM genes.

Article Synopsis
  • Pathogenic variants in the desmoplakin (DSP) gene are linked to a specific type of arrhythmogenic cardiomyopathy, which increases the risk of serious heart rhythm issues, but current evaluation methods are unreliable for these patients.
  • A study was conducted with patients from the DSP-ERADOS registry to track the occurrence of sustained ventricular arrhythmia (VA) over time, using a detailed statistical analysis to create a new clinical prediction tool.
  • The research identified five key clinical factors that can help predict the risk of developing sustained VA, resulting in a new DSP risk score that demonstrated strong prediction capabilities in both the initial and external testing groups.

Familial hypercholesterolemia (FH) is a genetic disorder affecting the metabolism of lipoprotein, characterized by elevated levels of plasma concentrations of low-density lipoprotein cholesterol (LDLC). The most common FH cause is mutations within the gene that encodes for the LDL receptor (LDLR) protein. Two induced pluripotent stem cell (iPSC) lines were generated from patients with FH, each carrying a single heterozygous mutation in the LDLR gene, one is a missense mutation, c.

Purpose: High costs of applying to genetic counseling graduate programs (GCGPs) are likely a barrier to workforce diversification. We sought to determine application costs and assess differences between individuals of historically underrepresented racial and ethnic backgrounds in medicine (hURM) and non-hURM applicants.

Methods: Applicants to GCGPs between 2005 to 2020 were surveyed about application history, related expenses, volunteer hours, and financial resources; 383 responses were analyzed.

Multiplexed assays of variant effect (MAVEs) have emerged as a powerful approach for interrogating thousands of genetic variants in a single experiment. The flexibility and widespread adoption of these techniques across diverse disciplines have led to a heterogeneous mix of data formats and descriptions, which complicates the downstream use of the resulting datasets. To address these issues and promote reproducibility and reuse of MAVE data, we define a set of minimum information standards for MAVE data and metadata and outline a controlled vocabulary aligned with established biomedical ontologies for describing these experimental designs.

Rare structural variants (SVs) - insertions, deletions, and complex rearrangements - can cause Mendelian disease, yet they remain difficult to accurately detect and interpret. We sequenced and analyzed Oxford Nanopore long-read genomes of 68 individuals from the Undiagnosed Disease Network (UDN) with no previously identified diagnostic mutations from short-read sequencing. Using our optimized SV detection pipelines and 571 control long-read genomes, we detected 716 long-read rare (MAF < 0.

APOE codes for apolipoprotein E (ApoE), which plays an important role in lipid and lipoprotein metabolism and homeostasis of tissue lipid content. Several variants in APOE have been associated with inherited dyslipidemias, and a subsequent increased risk of developing premature coronary artery disease (CAD). However, these variants and their impact on risk can be thought of on a spectrum, with some being more monogenic in nature, and others contributing in a polygenic/multifactorial manner.

Regional Variation in Cardiovascular Genes Enables a Tractable Genome Editing Strategy.

Circ Genom Precis Med

Division of Cardiovascular Medicine (V.A.K., R.H.W., N.S.T., N.Y., H.N.D.J., S.S., Y.H., C.M.R., M.T.W., E.A.A., V.N.P.).

Background: To realize the potential of genome engineering therapeutics, tractable strategies must be identified that balance personalized therapy with the need for off-the-shelf availability. We hypothesized that regional clustering of pathogenic variants can inform the design of rational prime editing therapeutics to treat the majority of genetic cardiovascular diseases with a limited number of reagents.

Methods: We collated 2435 high-confidence pathogenic/likely pathogenic (P/LP) variants in 82 cardiovascular disease genes from ClinVar.

Knowledge and attitudes on implementing cardiovascular pharmacogenomic testing.

Clin Transl Sci

March 2024

Clinical Genomics Laboratory, Stanford Medicine, Palo Alto, California, USA.

Pharmacogenomics has the potential to inform drug dosing and selection, reduce adverse events, and improve medication efficacy; however, provider knowledge of pharmacogenomic testing varies across provider types and specialties. Given that many actionable pharmacogenomic genes are implicated in cardiovascular medication response variability, this study aimed to evaluate cardiology providers' knowledge and attitudes on implementing clinical pharmacogenomic testing. Sixty-one providers responded to an online survey, including pharmacists (46%), physicians (31%), genetic counselors (15%), and nurses (8%).

Article Synopsis
  • The study explores how hypoxia affects blood vessel behavior in pulmonary arterial hypertension (PAH) through a genetic and epigenetic mechanism involving HIF-2α.
  • HIF-2α enhances the expression of certain genes and long noncoding RNAs that contribute to increased vascular dysfunction, creating a feedback loop that further boosts HIF-2α activity.
  • A specific genetic variant (rs73184087) is linked to an increased risk of PAH; interventions that either inhibit this pathway or reduce HIF-2α levels showed protective effects against the disease in animal models.

Genetic counseling and genetic testing are essential for individuals with congenital heart disease/defects (CHD/CHDs). However, the clinical practices of genetic counselors (GCs) and their preferences for different CHD genetic testing strategies are previously unexplored. To address these gaps, GCs (n = 112) representing diverse specialties completed an online survey regarding their counseling and testing practices for syndromic CHD and apparently isolated/non-syndromic CHDs (iCHD).

Background And Aims: Emery-Dreifuss muscular dystrophy (EDMD) is caused by variants in EMD (EDMD1) and LMNA (EDMD2). Cardiac conduction defects and atrial arrhythmia are common to both, but LMNA variants also cause end-stage heart failure (ESHF) and malignant ventricular arrhythmia (MVA). This study aimed to better characterize the cardiac complications of EMD variants.

Severe forms of dilated cardiomyopathy (DCM) are associated with point mutations in the alternative splicing regulator RBM20 that are frequently located in the arginine/serine-rich domain (RS-domain). Such mutations can cause defective splicing and cytoplasmic mislocalization, which leads to the formation of detrimental cytoplasmic granules. Successful development of personalized therapies requires identifying the direct mechanisms of pathogenic RBM20 variants.
