Summaries for Spermatogenic Failure, Y-Linked, 2

OMIM® : 57 About 2 to 3% of human males are infertile because of defects in sperm function, primarily due to oligozoospermia (defined as less than 10-15 million sperm per mL of semen) or azoospermia (Hull et al., 1985). (415000) (Updated 20-May-2021)

MalaCards based summary : Spermatogenic Failure, Y-Linked, 2, also known as spermatogenic failure, nonobstructive, y-linked, is related to phelan-mcdermid syndrome and partial deletion of y. An important gene associated with Spermatogenic Failure, Y-Linked, 2 is USP9Y (Ubiquitin Specific Peptidase 9 Y-Linked). Affiliated tissues include testis, and related phenotype is azoospermia.

Disease Ontology : 12 A male infertility characterized by nonobstroctive azoospermia or oligozoospermia that has material basis in interstitial deletions on the Yq11.221 chromosomal region.

UniProtKB/Swiss-Prot : 72 Spermatogenic failure Y-linked 2: A disorder resulting in the absence (azoospermia) or reduction (oligozoospermia) of sperm in the semen, leading to male infertility.
