OBSCN and familial dilated cardiomyopathy: In a study by Marston et al., WES was performed on 30 patients with DCM, and five potentially disease-causing OBSCN variants (p.Glu963Lys, p. Val2161Asp, p. Phe2809Val, p. Asp5966Asn, and p. Arg4856His) were identified in four patients (Marston et al., 2015).
