Genes linked to Heart-hand syndrome, Slovenian type
LMNA: Prelamin-A/C
The gene product produces lamins A and C, structural proteins that form the nuclear lamina beneath the inner nuclear membrane. Lamins help maintain nuclear shape and organize chromatin, and LMNA variants are associated with muscular dystrophy, cardiomyopathy, lipodystrophy, and premature-aging syndromes.
6 disease-causing and 31 uncertain variants in LMNA are linked to Heart-hand syndrome, Slovenian type.
Where Heart-hand syndrome, Slovenian type variants cluster
- LMNA Coil 2 (positions 243–383): 3 of 6 disease-causing changes, 2.4× more than its size predicts.

About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
