An important gene associated with Meier-Gorlin Syndrome 1 is ORC1 (Origin Recognition Complex Subunit 1), and among its related pathways/superpathways are Cell Cycle, Mitotic and Assembly of the pre-replicative complex. Affiliated tissues include bone and testes, and related phenotypes are failure to thrive and delayed skeletal maturation
