Genes affected

NANOS1 (HGNC:23044): (nanos C2HC-type zinc finger 1) This gene encodes a CCHC-type zinc finger protein that is a member of the nanos family. This protein co-localizes with the RNA-binding protein pumilio RNA-binding family member 2 and may be involved in regulating translation as a post-transcriptional repressor. Mutations in this gene are associated with spermatogenic impairment. [provided by RefSeq, Sep 2015]

NANOS1 Gene-Disease associations (from GenCC):

male infertility with azoospermia or oligozoospermia due to single gene mutation
Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
