RBMY1B

Chr Y

RNA binding motif protein Y-linked family 1 member B

The protein is an RNA-binding protein that functions as a splicing factor during spermatogenesis and is required for sperm development. Mutations in this gene cause male infertility due to azoospermia or severe oligospermia. The gene is located on the Y chromosome and follows Y-linked inheritance, affecting only males.
