Also, this first detailed coverage of sequence diversity and structure of the LHB/CGB gene cluster will pave the way for studying the identified polymorphisms as well as potential genomic rearrangements in association with an individual's reproductive success..     ///    "To shed light on these issues, we have re-sequenced the human Luteinizing Hormone/Chorionic Gonadotropin beta (LHB/CGB) cluster (19q13.32) of three population samples (Estonians, Mandenka, and Han). "    ///    The LHB/CGB cluster consists of seven duplicated genes critical in human reproduction.     ///    "In the LHB/CGB region, high sequence diversity, concentration of gene-conversion acceptor sites, and strong LD colocalize with peripheral genes, whereas central loci are characterized by lower variation, gene-conversion donor activity, and breakdown of LD between close markers.
