PMID: 30354339 (2018) - NKX2.5 variant segregated with disease in one large Icelandic family (11 affecteds with the variant, 12 unaffecteds with the variant - some young). Not in GnomAD but in 1/7100 Icelanders (0.0001 pop freq)

PMID: 28690296 (2017) - Cohort of sporadic adult onset DCM, 2 unrelated individuals with novel variants (absent in their control cohort and GnomAD), functional analysis show significantly reduced transcriptional activity and downstream impact on targets GATA4 and TBX20.

PMID: 25503402 (2015) - Cohort of idiopathic DCM, one family with novel variant (absent in GnomAD), segregated with disease in 3 affected family members (3 meiosis, 2 siblings and a child). Functional analysis revealed significantly reduced transcriptional activity

PMID: 27855642 (2016) - Two unrelated families with multiple affecteds. Same residue, alternate changes, both absent in GnomAD. Non-segregation mentioned, reduced penetrance stated explanation.

DCM in 2 individuals in a family with a nonsense variant (p.(Gln195*)) (absent in gnomAD)

- proband's sister and daughter also presented with congenital atrial septal defect (ASD)
