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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_199461.4.
• BS2: High AC in GnomAd at 15 AD gene.
