Genes affected

KASH5 (HGNC:26520): (KASH domain containing 5) Predicted to enable dynein complex binding activity. Predicted to be involved in several processes, including cytoskeleton organization; homologous chromosome segregation; and spindle localization. Predicted to act upstream of or within double-strand break repair via homologous recombination; oogenesis; and spermatogenesis. Predicted to be integral component of membrane. Predicted to be part of meiotic nuclear membrane microtubule tethering complex. Predicted to be active in chromosome; meiotic spindle pole; and nuclear outer membrane.
