Oculodentodigital dysplasia (ODDD) is a rare autosomal dominant inherited disorder mainly affecting the development of the face, eyes, dentition, limbs, hair and heart. GJA1 (the gap junction protein α-1) has been determined to be a causative gene of ODDD, mapped to chromosome 6q22-24 identified as the connexin 43 gene (Cx43). We found a novel GJA1 mutation (W25C) as the possible causative gene in this sporadic ODDD patient with neurological features of motor deficits by pyramidal tract signs, and sensory deficits due to peripheral nerve disturbance. It is also notable that the MRI of this patient demonstrated widespread aberrant signal lesions in the brain and brainstem.

Limb abnormalities are the second most frequent birth defects seen in infants, after congenital heart disease. Over the past 150 years, more than 50 classifications for limb malformations based on morphology and osseous anatomy have been presented. The goal of the current study is to investigate the genetic basis of congenital limb abnormalities in the Pakistani population.

Atrial fibrillation (AF) signifies the most prevalent supraventricular arrhythmia in humans and may lead to cerebral stroke, cardiac failure, and even premature demise. Aggregating strong evidence points to genetic components as a cornerstone in the etiopathogenesis of familial AF. However, the genetic determinants for AF in most patients remain elusive.

Article Synopsis
- Cerebral edema, a serious complication of acute ischemic stroke, significantly affects recovery and has been linked to p38MAPK, which promotes nerve cell death.
- The study investigated the effects of the p38MAPK inhibitor SKF-86002 on brain damage and edema in mice, using various staining and analysis methods to measure outcomes like neuronal apoptosis and blood-brain barrier permeability.
- Results showed that SKF-86002 reduced brain damage and edema, suppressed astrocyte proliferation, and lowered oxidative stress and inflammation by inhibiting specific signaling pathways, indicating its potential as a new treatment for ischemic stroke injury.

Endothelial injury is a fundamental pathogenesis of coronary atherosclerotic heart disease (CHD). Circular RNAs (circRNAs) are important post-transcriptional regulators in many human major diseases, including CHD. The aim of the present study was to explore the role of circ_0049979, a novel identified circRNA from ANO8 gene locus, in endothelial injury during CHD.
