Genes affected

RAD21L1 (HGNC:16271): (RAD21 cohesin complex component like 1) Predicted to enable chromatin binding activity. Predicted to be involved in mitotic sister chromatid cohesion; replication-born double-strand break repair via sister chromatid exchange; and synaptonemal complex assembly. Predicted to act upstream of or within several processes, including double-strand break repair via homologous recombination; homologous chromosome segregation; and seminiferous tubule development. Predicted to be located in lateral element. Predicted to be part of nuclear meiotic cohesin complex and nuclear mitotic cohesin complex. Predicted to be active in synaptonemal complex.
