The Association Between the rs2200733 SNP and Atrial Fibrillation Among Arabs: A Study from Jordan.

Introduction: Atrial fibrillation (AFib) is a common disorder featured by an irregular and fast heartbeat. The etiology of AFib is complex and involves genetic and environmental factors. The rs2200733 single nucleotide polymorphism (SNP) is located in close proximity to the promoter of paired-like homeodomain transcription factor 2 (PITX2) which plays a role in heart development.

COVID-19 and severe pulmonary alveolar proteinosis (PAP): A case report.

Background: Pulmonary alveolar proteinosis (PAP) is a rare lung disease that mainly presents with dyspnea. PAP diagnosis can be easily missed in the background of a coronavirus disease 2019 (COVID-19) infection, due to the similarity of their presentation and radiological findings. We present a case report of a post-COVID-19 patient, who later developed severe PAP.
