Restrictive dermopathy

Restrictive dermopathy (RD) is a rare, lethal autosomal recessive skin condition characterized by syndromic facies, tight skin, sparse or absent eyelashes, and secondary joint changes.^[2]: 563

Restrictive dermopathy is inherited in an autosomal recessive manner[1]
Specialty	Medical genetics

Mechanism

Restrictive dermopathy (RD) is caused either by the loss of the gene ZMPSTE24, which encodes a protein responsible for the cleavage of farnesylated prelamin A into mature non-farnesylated lamin, or by a mutation in the LMNA gene. This results in the accumulation of farnesyl-prelamin A at the nuclear membrane.^[3] Mechanistically, restrictive dermopathy is somewhat similar to Hutchinson–Gilford progeria syndrome (HGPS), a disease where the last step in lamin processing is hindered by a mutation that causes the loss of the ZMPSTE24 cleavage site in the lamin A gene.^{[citation needed]}
