Genes linked to Restrictive dermopathy 2
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.
1 disease-causing and 17 uncertain variants in LMNA are linked to Restrictive dermopathy 2.
Known disease-causing variants in Restrictive dermopathy 2
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| LMNA R335W | 335 | IF rod | Disease-causing (★★) |
Same protein, different disease
- Charcot-Marie-Tooth disease is also caused by LMNA variants; they fall mostly in different places as the Restrictive dermopathy 2 variants (130 disease-causing).
- Dilated cardiomyopathy is also caused by LMNA variants; they fall mostly in different places as the Restrictive dermopathy 2 variants (21 disease-causing).
- Familial partial lipodystrophy, Dunnigan type is also caused by LMNA variants; they fall mostly in different places as the Restrictive dermopathy 2 variants (13 disease-causing).
- Emery-Dreifuss muscular dystrophy is also caused by LMNA variants; they fall mostly in different places as the Restrictive dermopathy 2 variants (12 disease-causing).
- Congenital muscular dystrophy due to LMNA mutation is also caused by LMNA variants; they fall mostly in different places as the Restrictive dermopathy 2 variants (11 disease-causing).

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.
