My adult son has Renpenning syndrome. My daughter, who is healthy, gave birth to a son three years ago with the same. We recently learned that this condition is genetic. I would like to learn more about this condition. Are speech delays common in Renpenning syndrome? Do individuals with this condition require less sleep than average? Could my family, which has French Canadian heritage, be related to the Canadian family described by Renpenning in the 1960s? What can we expect? See answer
