JH1 Jersey Haplotype 1 (JH1F = Not carrier, JH1C = Single carrier, JH1S = Double carrier) JH1 is an autosomal Read more (JH1F = Not carrier, JH1C = Single carrier, JH1S = Double carrier) JH1 is an autosomal recessively inherited defect. The disorder was identified in the North American and the Nordic Jersey populations, however the frequency was somewhat lower in the Nordic population. JH1 primarily causes early embryonic death (spontaneous abortion), within the first 60 days of gestation. The key ancestor is believed to be Observer Chocolate Soldier (US 596832). https://omia.org/OMIA001697/9913/ JH1F Free
