Project description:Different single mutations on the same sarcomeric gene often cause distinct cardiomyopathy phenotypes as dilated (DCM) or hypertrophic cardiomyopathy (HCM). The key factors involved in this disease divergence is unknown and could be key for disease intervention.We generated isogenic familial DCM and HCM disease-specific human embryonic stem cells (hESCs) carrying the cTnT-DK210 and -DE160 mutation, respectively. Whole transcriptomic RNA-sequencing was used to identify the key gene involved in the earliest disease divergence of cTnT-DK210 caused DCM and cTnT-DE160 caused HCM. Results provide insight into the new molecular mechanisms underlying familial dilated cardiomyopathy.

Project description:Exome sequencing of dilated cardiomyopathy
Project description:Importantly, mutations in nuclear envelope-encoding genes are the second-highest cause of familial dilated cardiomyopathy. One such nuclear envelope protein that causes cardiomyopathy in humans and affects mouse heart development is Lem2. However, its role in mechanically active tissue such as heart remains poorly understood.
