Loss-of-function mutations in centrosomal protein 112 is associated with human acephalic spermatozoa phenotype.

Acephalic spermatozoa, characterized by the headless sperm in the ejaculate, is a rare type of teratozoospermia. Here, we recruited two infertile patients with an acephalic spermatozoa phenotype to investigate the genetic pathology of acephalic spermatozoa. Whole-exome sequencing analysis was performed and found mutations in CEP112 in the two patients: homozygous mutation c.
