    ### Instruction:
    What are the genetic changes related to sudden infant death with dysgenesis of the testes syndrome ?
    ### Response:
    A single mutation in the TSPYL1 gene has caused all identified cases of SIDDT. This gene provides instructions for making a protein called TSPY-like 1, whose function is unknown. Based on its role in SIDDT, researchers propose that TSPY-like 1 is involved in the development of the male reproductive system and the brain.
