ALPK3 Truncating Variants Cause Autosomal Dominant Hypertrophic Cardiomyopathy

In hypertrophic cardiomyopathy, heart muscles are thicker, which can make it harder for the heart to receive and pump blood. While in most cases the condition will not affect daily life, it can cause heart failure and is frequently cited as the most common cause of sudden unexpected death in young people. More...

CD8 T-Cell–Predominant Lymphocytic Esophagitis Associated with GERD

In patients with reflux esophagitis (RE), increased lymphocytes are often part of a mixed inflammatory infiltrate that also includes eosinophils and/or neutrophils. Less frequently, lymphocytes are the only type of inflammatory cells associated with gastroesophageal reflux disease (GERD). More...
