Lethal Congenital Contracture Syndrome 4, also known as lccs4, is related to lethal congenital contracture syndrome and distal arthrogryposis. An important gene associated with Lethal Congenital Contracture Syndrome 4 is MYBPC1 (Myosin Binding Protein C1), and among its related pathways/superpathways are Cardiac conduction and Striated muscle contraction pathway. Affiliated tissues include skeletal muscle, and related phenotypes are respiratory insufficiency and flexion contracture
