Genes affected

PRM1 (HGNC:9447): (protamine 1) Predicted to enable DNA binding activity. Predicted to be involved in DNA packaging. Predicted to act upstream of or within nucleus organization and spermatid development. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

RMI2 (HGNC:28349): (RecQ mediated genome instability 2) RMI2 is a component of the BLM (RECQL3; MIM 604610) complex, which plays a role in homologous recombination-dependent DNA repair and is essential for genome stability (Xu et al., 2008 [PubMed 18923082]).[supplied by OMIM, Nov 2008]
