An important gene associated with Spermatogenic Failure 1 is SYCP2 (Synaptonemal Complex Protein 2), and among its related pathways/superpathways is Regulation of expression of SLITs and ROBOs. Affiliated tissues include brain and spleen, and related phenotypes are male infertility and oligozoospermia
