Red List (low evidence)

ClinGen curation: Two probands reported in a single 2010 publication (Wang et al, PMID 20970104). Two unique missense variants were reported in this publication. The pathogenicity of one variant was supported by functional studies in a cell culture model system that showed mutant protein fragments accumulated in the cytoplasm and failed to bind to actin filaments. This variant also segregated with disease in 2 additional family members. The second variant reported by Wang et al. was found at a high frequency in the ExAC database, which is consistent with benign variation. The mechanism for disease is unknown. This gene-disease association is supported by a cell culture model system, expression studies and localization of NEXN to the intercalated disk (Hassel et al, 2009, PMID 1988149; Somi et al, 2016, 27148881), and interaction with alpha actin (Wang et al, PMID 20970104).
In summary: one family plus functional data.
