Implications for lncRNAs in the central nervous system: Transcriptional dysregulation is a key contributor to the pathogenesis of a wide range of diseases and long non-coding RNAs(lncRNAs) are highly expressed in the nervous system. Indeed, amongst the over 50,000 lncRNAs expressed in the human genome, more than 40% are specifically expressed in the brain where their roles in brain development, neuron functions, maintenance,

sinus venosus defect(sVD) accounts for 4%–11% of all atrial septal defects(AsD) and may present with dyspnea, heart failure(HF), palpitations, or angina.^[1] The malformation typically involves an interatrial communication due to a deficiency in the common wall connecting the right pulmonary veins and the superior vena cava(sVC) and often accompanies anomalous pulmonary venous connection of some or all of the pulmonary veins.
