“…The isolated form of LVNC occurs in the absence of other structural heart disease, and the other form occurs in association with other congenital heart defects [Ichida et al, 2001; Markiewicz‐Łoskot et al, 2006; Xia et al, 2008]. Clinical and genetic heterogeneity have been clearly demonstrated since autosomal dominant, recessive, and X‐linked genes have been implicated as causal agents [Digilio et al, 1999; Sasse‐Klaassen et al, 2004; Brady et al, 2006; Xing et al, 2006; Stöllberger and Finsterer, 2007; Finsterer et al, 2008; Moric‐Janiszewska and Markiewicz‐Łoskot, 2008; Vijayvergiya et al, 2008]. LVNC has been frequently reported in association with several neuromuscular disorders [Bleyl et al, 1997; Finsterer et al, 2005; Stöllberger and Finsterer, 2005; Spencer et al, 2006; Finsterer et al, 2007a,b; Stöllberger et al, 2007].…”
