Family studies showed that an Arg145Gly mutation was linked to HCM and a Lys206Gln mutation had occurred de novo, thus strongly suggesting that cTnI is the seventh HCM gene.

Two siblings in a pedigree without cardiomyopathy were wild-type at the HFE C282Y locus; although the brother harboured a single copy of the 187C-->G (H63D) allele, segregation analysis showed that in neither sibling was the iron-storage disease linked to MHC Class I markers on chromosome 6p.
The emerging data are quite conflicting and do not provide definitive evidence for a role of these gene variants in the pathogenesis of IHD; a possible exception is the G252A and polymorphism in the TNF-beta gene (also known as lymphotoxin-alpha) which, in a comprehensive genome-scan linkage analysis of unrelated Japanese, but not in a smaller German population, was linked to myocardial infarction.

We have characterized the causative factor VIII mutation, HLA alleles as well as 4 polymorphisms (-827C>T, -308G>A, -238A>G, and 670A>G) in the TNFA gene in 164 patients (124 severe, 26 moderate, and 14 mild) in 78 families with hemophilia A enrolled in the Malmö International Brother Study (MIBS).
Initially, association with T1D was seen for LT-alpha A1069G (intron A, p=0.011, rs909253) and TNF G(-308)A (p<1x10(-5), rs1800629), but no association was observed for TNF G(-238)A (rs361525).
